Opening the case, reading the m/b:
K9A2 Platinum MSI
I hadnt been paying much attention to this thread, but just to let you
know that I also saw the same thing on this machine which has an MSI
790FX
Platinum motherboard. It was also irq22, and I am also running amd64.
In my case I simply disabled the onboard ethernet (which I wasnt using)
and the problem went away - but then I only saw the problem once, it
wasnt
a regular occurrance. If you have an alternative ether card you can drop
in thn you could try that...
FYI, this box has always run off an ethernet card (fxp). The on-board
NIC (re) was enabled. After disabling, the ethernet storms persisted.
trouble with onboard re(4) was resolved in -CURRENT and -STABLE, but
storms are not bound to ethernet only. storm may appear on any device.
if any device generates enough interrupts rate, storm will arrive.
I've written about it in
http://lists.freebsd.org/pipermail/freebsd-stable/2009-January/047644.html
so far i can say that this issue is related on MSI IXP600 based
motherboards only. well, we should try to find out what we can do to
resolve it.
