Greetings, respected Kernel-gurus ;-)
I have been experiencing hard system lockups (I cannot get it to respond to
*anything*, including CtrlAltDel, pings, etc.) when performing moderately
heavy disk access under 2.3 kernels. The problem seemed to have gotten
better with 2.3.99-pre5, but apparently has been entirely fixed.
Any action requiring a significant amount of disk access to a device on my
Promise UltraDMA/66 controller runs a risk of locking up the entire system.
This includes simple tasks like gzipping a large (usually has to be >100MB)
file. Extensive swapping has also created this effect, so it doesn't seem
to be filesystem-related. Ripping CD images or burning a CDR also exhibit
this behavior, as well as playing a DVD movie.
My system is a dual PII/350, 256MB RAM, RivaTNT (does not seem to be related
as it breaks just as quickly at the prompt as in X), Promise UltraATA/66 PCI
controller. The disks affected are on the Promise: WDC18000D, HP 7500i CDR,
Creative Encore PC-DVD x2.
Please Cc: or direct any questions to me, as I am not on this list.
(P.S. - unrelated side note... kswapd seems to be consuming large amounts
of CPU time (>80% of one CPU) at times when it isn't even swapping anything.
This is new behavior with 2.3.99-pre6. At least it doesn't lock my system,
though. ;-)
Thanks for your time.
Ethan
