Hi Marc and List,
i had similar issues with FreeBSD 7.2-PRERELEASE. Server (zfs,nfs)
seems to hang in intervals of about 8 hours.
kernel is still there but no connections can be made to nfs/ssh and
login on local console doesn't seem to
work due to incredible slowness. breaking to the debugger takes a
moment but works.
(compiling kernel with WITNESS didnt help)
the server had been solid before with 7 stable kernel from around 19
October 2008.
I now added these lines to /boot/loader.conf
hw.pci.enable_msi=0
hw.pci.enable_msix=0
to disable Message Signaled Interrupts. Which are used by the 3ware
twa driver and igb network driver on our server.
If you are willing to test further on your server, it may be helpful if
you could determine which of those two lines in loader.conf fixes the
problem for you. It would also be useful to provide a dmesg from the
machine when both msi and msix are enabled.
FWIW, looking at the "vmstat -i" output it appears that only the igb
driver that are using MSI/MSIX, unless you have a reason to suspect
otherwise?
How do you tell that, about igb? looking at the server I have the igb
device on, it doesn't seem to say anything about that ...

The server(s) that I am experiencing the hangs on, vmstat -i shows:
# vmstat -i
interrupt total rate
irq1: atkbd0 2 0
irq3: sio1 8 0
irq25: bge0 4614816 213

cpu1: timer 43116889 1997
Total 92681163 4293
Are any of these similiarly using MSI/MSIX?
