using 2.4.13 I still experience crashes when a very specific set of
programs are used.
as I have a Abit BP6 and it's known to be not the best SMP board, I was
wondering if it could be possible that a high rate of interrupts
(specific IRQ's) could cause the 'crashes' I experience.
The setup is really weird. I use freeamp to play streams; I have an
ethernet card connected to a 512kbits adsl router; I use an SB16 under
opensound.com and use X with an AGP card.
if the stuff 'crashes, it in fact doesn't crash but starts to become
_very_ slow. if you look at /proc/interrupts you would see timer ticks
increase one by one but it woud take ages. like one tich in hald an hour
or so. this basically means -- system unuseable. it does respond to
pings though.
my wild guess is that the combination and rate of interrupts cause the
well known

entries that finally after some time hit a combination that causes the
system to become very slow. would that be a possibility or am I just (as
usual :-) wrong ?

anyways, it basically only happens when I use X, when I use sound, when
I use xmms _and_ it comes from eth0. it happens not directly but
sometimes, after, say an hour, sometimes after 4 hours.
(fwiw -- it also happens under the opensound drivers in the kernel but
less frequent)
