Subject2.4.19 Oops' and crashes
	Hi all,

I'm facing regular kernel crashes with 2.4.19 (stable) on my COMPAQ Armada
M700 Laptop: PIII@750MHz/256Mb SDRAM/10GB IDE HDD with ext2.

After running it for a while (upto 2 hours) make, top and some other
programs start segfaulting the moment I execute them, while some (ls,
ping) still work. I've noticed a continuous increase in memory and
swap utilization (upto the point all 256M is nearly utilized),
even if I'm not running anything memory-intensive.
When I try to restart, I get an oops on the console. This machine's been
running 2.2.16 for the past 6 months without any problems.

ksymoops 2.4.5 on i686 2.4.19-rc5. Options used
-V (default)
-k /proc/ksyms (specified)
-l /proc/modules (specified)
-o /lib/modules/2.4.19-rc5 (specified)
-m /boot/System.map-2.4.19-rc5 (specified)
