Hello list,
i've 36 servers all running vanilla 3.18.18 kernel which have a very
high disk and network load.
Since a few days i encounter regular the following error messages and
pretty often completely hanging disk i/o:
[535040.439859] do_IRQ: 0.126 No irq handler for vector (irq -1)
All systems are Single E5 Xeons and I'm running irqbalance on them.
Does it stop if you disable irqbalance ?
No. The machines still crash.
crash as in running into a BUG? Or is it just that disk I/O is stalled?
Sorry i meant I/O is stalled. It crashes to me as i can't login anymore
due to hanging I/O.
Can you please provide the full dmesg output of such a machine?
Yes (this time from a machine using 3.18.14) =>
http://pastebin.com/raw.php?i=S6kAk0iS
I'll cook up a debug patch for that against 3.18.18.
Do you have any special upstream commits in mind?
Stefan
That would be great!
Stefan
Thanks,
tglx
