I am parsing chunks of pos-tagged text in JupyterLabs.
NLTK can run on Python<3.5 and >3.8 according to its faq.
I can return pos-tagged text just fine. But when I want to return parsed chunks, it crashes python.
I am running MacOS 11.1, Python 3.8.6, Jupyterlab 3.0.0, and nltk 3.5
from nltk import *
text = """The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital
computer or the gears of a cycle transmission as he does at the top of a mountain
or in the petals of a flower. To think otherwise is to demean the Buddha...which is
to demean oneself."""

"""
chunker = RegexpParser(grammar)
toks = word_tokenize(text)
postoks = pos_tag(toks)
All is fine until I want to parse the chunks with RegexpParser. At which point, it crashes the kernel.
chunker.parse(postoks)

I have a basic python3 script for running a ping sweep using kamene with two main issues. I'm not sure if they are related so I'll add them both in the same post.
Where in here is the main issue and what have I done wrong?
First issue...
When I import IP and ICMP from kamena.all I have an error as below...
No name 'IP' in module 'kamene.all'pylint(no-name-in-module)
No name 'ICMP' in module 'kamene.all'pylint(no-name-in-module)
Second issue...
When I run the program, I get an IPv6 error and then a segmentation fault with a warning from OSX to say that python has stopped.
python3 pingsweep.py
WARNING: No route found for IPv6 destination :: (no default route?). This affects only IPv6
Segmentation fault: 11
This is my script code...
from kamene.all import sr1,IP,ICMP
for ip in range(1, 8):
packet = IP(dst="192.168.0." + str(ip), ttl=20) / ICMP()
reply = sr1(packet, timeout=2)
if not (reply is None):
print(reply.dst)
I have installed kamene with...
pip3 install kamene
Lastly, the crash report from OSX...

I cannot reproduce your issues with Scapy, so I'll assume that's only related to Kamene (I have edited your question to reflect that).
You can either try using the "real" Scapy (https://github.com/secdev/scapy), or report this issue to the Kamene project.
This happens due to permissions issue with mac. The python program is not able to get write to the packet on to network. I had a similar issue and using sudo resolved the issue.
I am working on a driver for a custom piece of hardware (Xilinx FPGA based) and am having difficulty picking up the interrupt it is sending. The old system ran uCOS-II and just registered the interrupt ID 94. When I register that interrupt in Linux, it never triggers even though I know the hardware is sending the signal.
Is there something besides calling register_irqthat I need to do?
Is there a way for me to see all interrupt signals sent to the CPU even if nothing has registered for them?

Welcome to Linaro 14.04 (GNU/Linux 4.9.0 armv7l)
Which driver are you using, your custom driver or Xilinx GPIO?
As I understand you hardcoded Linux IRQ number 94 in register irq?
94: 0 0 zynq-gpio 48 Level my_int_handle
I would say that you have to declare your GPIO node as interrupt controller in the device tree with appropiate interrupt property, because driver uses that information for interrupt:
gpio->irq = platform_get_irq(pdev, 0);
I'm not sure of the exact IRQ number mapping.
Device tree node for GPIO controller on Zynq looks like this:
gpio#e000a000 {
#gpio-cells = <2>;
#interrupt-cells = <2>;
compatible = "xlnx,zynq-gpio-1.0";
clocks = <&&clkc 42>;
gpio-controller;
interrupt-controller;
interrupt-parent = <&&intc>;
interrupts = <0 20 4>;
interrupt-controller;
#interrupt-cells = <2>;
reg = <0xe000a000 0x1000>;
};
If you use hardcoded Linux IRQ number instead of device tree, you can try to find it with probe_irq_on/off();
I am encountering the messages below after creating an UBIFS filesystem in
a new UBI volume on an existing UBI partition.
This happens while reading all the files on the UBI fs via tar -cf /dev/null *:

The rate of reproduction is one in about 20 sequences of: ubirmvol,
ubimkvol (256MB), unpack a rootfs.tgz (20MB, 40MB unpacked) in the
mounted UBIFS, umount, ubidetach, sync, reboot. There are no xattrs
created. No power cuts happen during the tests.
The board runs a 3.18.80 kernel on an ARM board. I tested other
identical test boards where only the NAND chip manufacturer was
different.
I had CONFIG_MTD_UBI_FASTMAP enabled when the error occured, but I
used no explicit fastmap boot cmdline option. I tried mounting the
ubifs with a rebuilt kernel that had the config option disabled after
the issue reproduced, but the read error still occured.
I also tried mounting with a kernel that had "ubifs: Fix journal
replay w.r.t. xattr nodes" patch [1] applied, after reading older similar error reports, but once reproduced on a NAND, the read error
persisted.
[1] https://patchwork.ozlabs.org/patch/713213/
Is there some special requirement except just umount, ubidetach and
sync before running reboot, or regarding free space fixup ? Would
creating the fs image offline with mkfs.ubifs instead of unpacking it
via tar make a difference here ? Would it help to test with
cherry picked commits from linux v4.14 that touch
fs/ubifs ?
I am trying to get a Matlab MEX to run in Linux. It uses FTDI's D2XX library v1.3.6 (Documentation).
FT_CreateDeviceInfoList(&ftdi_count) gives me an ftdi_count of 1, so the FTDI chip is detected.
However, when iterating through the device list from FT_GetDeviceInfoList(device_list, &ftdi_count), my FT_DEVICE_LIST_INFO_NODE structure is all zeros, so obviously the code cannot find the device with the description it is looking for:
(gdb) p *p_device
$3 = {Flags = 1, Type = 3, ID = 0, LocId = 0, SerialNumber = '\000' <repeats 15 times>,
Description = '\000' <repeats 63 times>, ftHandle = 0x0}
My first guess was that udev wasn't set up. But the problem persists with
SUBSYSTEM=="usb", ATTR{idVendor}=="0403", ATTR{idProduct}="6014", MODE="0666"
lsusb -v has access to the values:

iProduct 2 [company that provided me with their] Kit v3

[...]
What can I do to make the FTDI functions work?
The problem is that Linux automatically loads the VCP driver (ftdi_sio).
In the Question How can I get Linux device with FTDI D2XX driver API, Akira shows a udev script to from A blog unload that driver. I modified it to work with my FT232H chip, which has only one port:
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6014", RUN+="/bin/sh -c 'echo -n $kernel:1.0 > /sys/bus/usb/drivers/ftdi_sio/unbind;'"
We are facing an issue on which we need some help.
Brief write-up :
We have enabled SMP in Linux 2.6.39.4 kernel and cross compiled it for PPC-476. After booting, kernel is able to map both the processors (2 cores at h/w). The problem we are facing is, while running modprobe command repeatedly, one of the cpu goes into stall state. We have tried to dump stack of all active cpus (using sysrq) while one of the cpu is in stall state. The stack dump showed both the processors were executing same process (with same PID) i.e. modprobe.
Question :
1. is it possible for both the processors to be executing same process at a movement with same PID.
2. Is the execution of both process simultaneously give rise to some race condition which is causing either of CPU to go in stall state.

=============================================================
Both questions of yours are False. There is no possibility that two cores run the same task at the same moment.
From the OOPS/panic trace, we can know that kernel panic on CPU 0 first, then it triggered the SysRq to "Show backtrace of all active CPUs". That is to say, CPU 1 works good at the time CPU 0 panic, but CPU 0 exception triggered to dump the backtrace of CPU 1.
Now let us analysis why CPU 0 panic: from the backtrace, it happened during "modprobe", so please analysis the kernel modules on your system to locate the one that trigger the panic.
