All,
Attached is my first cut at addressing the problems described in this
thread. As I discussed earlier, the VM syncer thread is likely starving
the USB interrupt thread. This causes the shared usb+network
interrupt to remain masked, preventing network interrupts from being
delivered,
and thus triggering watchdog timeouts.
Just to be clear, has it been established that the problem only occurs
when em is sharing an interrupt? I have a lot of production machines
using the PDSMi board, which is one of the boards that the problem was
noticed on, however i do not share any irqs, i always disable USB in the
BIOS.
On many of our servers, we have bge cards and I can see a lot of
watchdog timeouts. We always disable USB in the bios and they didn't
share irq.
