Re: [OOPS] 2.4.13-ac5 default_idle [more info]

[Wenzhuo Zhang <wenzhuo@zhmail.com>]

More info:
It's a slackware-8.0 box.
# gcc --version
2.95.3
# ld -v
GNU ld version 2.11.90.0.19 (with BFD 2.11.90.0.19)

The motherboard is a Asus P/I-P55TP4N. And the CPU is Petium(classic)
100MHz.

I don't know whether it's a kernel issue or a hardware issue. Pls shed
light over it. Thanks

(The box crashed again when I was writing this message.)
