I've setup an home server, using an old HP ProLiant ML110G6 server,
with PVE6, kernel 5.3.18-2-pve.
I reveive, spuriously, logs like:
root@ino:~# grep do_IRQ /var/log/kern.log
Mar 1 05:10:51 ino kernel: [197698.269626] do_IRQ: 3.40 No irq handler for
vector

Mar 2 08:48:00 ino kernel: [297125.421168] do_IRQ: 2.40 No irq handler for
vector
Mar 2 08:52:01 ino kernel: [297366.060392] do_IRQ: 2.41 No irq handler for
vector
Mar 2 11:32:01 ino kernel: [306965.868404] do_IRQ: 0.39 No irq handler for
vector
Server work as expected, without any trouble, crash, ...
AFAI've understood, first numer is the core (i have 4), second is the
interrupt vector.
Googling around i've hit:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1781016
and effectively i've many 'serial' USB interfaces connected (2 USB
serial port, an APC UPS, a GSM dongle).
I've tried to, using the irq vecrot, to understand the peripheral, but
the command proposed:
grep 35 /sys/kernel/debug/irq/irqs/*
does not work, there's no more '/sys/kernel/debug/irq/irqs/*' interface
in sysfs.
Someone have some hint? Thanks.
