hi there,
every so often, my system (2.4.13 smp) gets really sloooooow. a typical top
looks something like:
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
5 root 14 0 0 0 0 RW 99.9 0.0 7:52 kswapd
7 root 9 0 0 0 0 SW 1.9 0.0 0:04 kupdated
2053 root 13 0 984 984 776 R 0.7 0.4 0:01 top
2063 p 9 0 2080 2080 1292 S 0.3 0.9 0:00 vim
kswapd is definitely not behaving correctly.
the thing that brought it on this time was gtv (an mpeg viewer which uses
sdl) bailed on me. X "kind of" froze, so i killed it. but that's only the
cause this time around. last time, it happened between the time of going to
bed and waking up (ie- the system was pretty much idling from a user's pov).
this has been happening with the 2.4.13 kernel every couple of days.
i thought i'd post it to lkml to let someone know that there's a problem.
i'm not subscribed to the list, so if there's anything else i can do to help
diagnose what's going on next time it happens, please cc me.
i feel like such a loser when i reboot. ;) i heard that 2.4.15 was just
released, so i'll try upgrading to that and see if it helps any.
pete

Don't use 2.4.15: it may corrupt your filesystem.
I just released 2.4.16-pre1 which has a fix for this problem...
Please try it and tell us if you still see the kswapd problems.

Hello
I have experienced similar behaviour with kswapd/kupdated with 2.4.12 and
2.4.13 . After much struggle, I discovered that the system had become
slugish and non-responsive because i was using the wrong IDE busmastering
and DMA drivers (VIA chipset) instead of the correct ones for my
motherboard (PROMISE chipset). If you are using IDE, then perhaps you have
something similar and are using the incorrect drivers?
If you are indeed using IDE then suggest that you turn of busmastering all
together and give it another try.

I am having the same problem with 2.4.6. I have the VIA Drivers compiled in,
which are the correct ones for my chipset. Perhaps it is a problem with the
VIA Drivers? I havn't tested it with anything else.

Could very well be... VIA chipset has been a bit of a snag for me in the
past.
