Yes, I just got another storm, on my ATA controller this time. Ah
well, so much for the idea of disabling unneeded devices!
-pete.
it's a kind of magic, really. I built a new kernel with KDB and
DDB and after 1 day, 13:15 I'm still waiting for storm to arrive.
And I added
hw.acpi.osname="Linux" to /boot/loader.conf.
Try doing lots of IO and you will get the problem soon. You might
want to try:
while true; do dd if=/dev/zero of=BAH bs=1M count=1024; sync; done
FWIW, last night I changed the address of the comm port IO in my
BIOS. Then I ran the Bacula regression test suite (lots of IO). For
my machine, once the interrupt storm starts, it continues. I do not
know if that happens to everyone.
Since changing the address, I have had no interrupt storms. I have
been running the above IO loop for about ten minutes.
No storm yet (knock on wood).
And it's back:
Jan 22 17:21:46 polo kernel: interrupt storm detected on "irq22:";
throttling interrupt source
Jan 22 17:23:19 polo kernel: interrupt storm detected on "irq22:";

throttling interrupt source
Jan 22 17:38:20 polo kernel: interrupt storm detected on "irq22:";

I shall try the hw.acpi.osname="Linux" option now.
