Hi Andrew
I'm experiencing a strange behaviour with 2.5.70-mm1 on my work PC,
Pentium IV 1.6GHZ with 512MB memory. Let me know if you need any more input.
After login in to KDE /proc/meminfo

Too much memory has gone to Slab. cat /proc/slabinfo follows bellow.
After a while the kernel hangs, and after rebooting my /var/log/messages
has this as the last output:
May 29 15:10:06 bongani1 last message repeated 689 times
May 29 15:10:06 bongani1 kernel: e:0x20
May 29 15:10:06 bongani1 kernel: lisa: page allocation failure. order:0, mode:0x20
I was running a couple of applications Mozilla-mail, KDE, Some Java Application Server ...
When I load the a application, some memory is freed from the Slabs. The PC was just
sitting there both times running those applications and both times I returned and found it
hanging.
cat /proc/slabinfo looks like this
