Red Hat Bugzilla – Bug 56658
(IDE ALI APM)multiple kernel hangs with Toshiba Satellite 1620 CDS (APM and BIOS related)
Last modified: 2008-08-01 12:22:51 EDT
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
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
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
