I upgraded from Squeeze to Buster last week and have been having a
problem with "No irq handler for vector" messages appearing in all the
console windows.
There were originally 3 different numeric values in the messages. After
adding 'pci=nomsi,noaer' to the grub boot options, 2 of them stopped.
I still get this more than 100 times per day.:
Message from syslogd@penguin at Mar 18 10:11:08 ...
kernel:[161132.371343] do_IRQ: 1.35 No irq handler for vector
The time between messages can be as little as 9 seconds, or more than 2
hours. The messages happen throughout the day, whether I'm at the
computer or not.
I've tried 'dmesg -n 2', 'dmesg -n 1', and even 'dmesg -D'. The messages
keep coming. I especially don't understand how 'dmesg -D' doesn't help,
as it's documented purpose is to 'Disable the printing of messages to
the console'.
The messages don't correlate to any other events I can find in the log
files.
On a long shot, I disconnected the optical drives, unplugged the UPS
from the USB port, and removed the TV capture card. None of that made a
difference.
Other than the messages, the system is running fine.
The system includes a Phemon II CPU and 16 GB RAM in a Gigabyte
890GPA-UD3H motherboard.
Any suggestions?
