This thread sort of seemed to get lost in a discussion about whether
or not Dominik has a dual-PII system or a dual-PPro system. I am very
much interested in whether anyone has seen the behavior he is
describing.
I am running the IMAP server component of a messaging system that I
developed for the university on a dual-PII 300 system with 256
megabyte of RAM. We have seen 2-3 networking stalls similar to what
Dominik has reported in the last month or so. Downing and upping the
interface brings the machine back to life.
The NIC cards are SMC Etherpower II's both sharing a single IRQ. I
have reported the behavior to Donald. Interestingly the non-stalled
NIC continues to function but both NICS need to be downed and upped in
order to restore operation.
We have also seen one instance of the fatal deadlock condition that
Leonard Zubkoff discusses in kernel/sched.c in the context of the
allow_interrupts function. I noticed in Alan's release notes that
there might be a fix forthcoming for this so I am very interested in
seeing the completed patch.
I didn't mean to interrupt the flow of the thread but this behavior
may be of interest to others running 2.0.x boxes in SMP production
environments.
