Subject[BUG]: 2.4.1-pre8: Wierd lockup with /proc based functions (?)
Just a while ago, my system just started acting funny. I couldn't use w,
top, ps, and then some of my X applications started to freeze too.
I couldn't even kill those hung processes because they'd hang too. So
When i tried to restart ctrl+alt+del, it did not kill the hung processes
and i had to hard restart.

I dont know what triggered it but here's my dmesg and motherboard
information:

Motherboard: AcerOPEN AP53/AX - Latest flash bios: R3.A0 (1997)
RAM: 64MB EDO: Kingston, 60ns

RTC & Battery: Dallas DS12887A - Ds12B887 compatable
(512KB?) Pipeline burst cache

*NOTE: This Pentium 200Mhz oddly has USB support (disabled right now).
It has first generation USB. 2 ports.
