Description ben.de.rydt 2001-11-23 16:16:00 UTC 
Description of Problem:

Suspend / Resume hangs the kernel/machine.

Every possible APM-related event f.i. low battery notification hangs the 
kernel/machine. When the CPU gets too hot, the fan starts running and the 
machine hangs (with a running fan). I suppose the BIOS tries to notice 
the kernel about the hot cpu.

What's meant with ``hang'': blank (black) screen, and no reaction on any 
key-combination.

This machine used to work with RedHat 6.2, stock RedHat 2.2.17 kernel. 
Suspend/Resume did work too.

The fix is: do not include the ALI chipset tuning into all kernels. The 
problem goes away when this code is turned off. You'll loose the DMA 
access to the HDD, but this is a lot better than random hangs.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
