All,
I'm seeing some patterns here with all of the network driver problem
reports, but I need more information to help narrow it down further.
I ask all of you who are having problems to take a minute to fill
out this survey and return it to Kris Kennaway (on cc:) and myself.
Thanks.
1. Are you experiencing network hangs and/or "timeout" messages on the
console? If yes, please provide a _brief_ description of the problem.
OK, next question, to all em users:
If your em device is using a shared interrupt, and you are NOT
experiencing timeout problems when using this device, please let me
know:
dalki# vmstat -i
interrupt total rate
irq4: sio0 2071 0
irq6: fdc0 10 0
irq14: ata0 47 0
irq20: ahd0 21755 4
irq23: em0 124751 23 <-- not a shared interrupt
irq24: ahd1 15 0
cpu0: timer 10453509 1999
Total 10602158 2027
tyan# vmstat -i
interrupt total rate
irq14: ata0 58 0
irq16: em0 fxp1 332832 851 <-- shared interrupt
irq18: fxp0 973 2
irq19: atapci1 132883 339
cpu0: timer 774308 1980
cpu1: timer 777136 1987
Total 2018190 5161
So far all of the em problems I have seen involve shared interrupts,
and conversely all em systems I have seen that do not have timeout
problems are not shared.

And so looks mine, FreeBSD 6.2-PRE/AMD64,
high I/O on disks and I/O on net renders this box unusuable ...
thor# vmstat -i
interrupt total rate
irq1: atkbd0 12437 1
irq6: fdc0 27 0
irq12: psm0 335285 42
irq14: ata0 215 0
irq17: fwohci0 1 0
irq20: atapci1 102616 12
irq21: ohci0+ 2 0
irq22: nve0 ehci0 7594338 956
irq23: pcm0 41007 5
cpu0: timer 31752206 3999
Total 39838134 5018
You don't appear to be using the em driver. Can you confirm?
Kris
positive.
