Description of problem:
kernel fails to determine IRQ for the IDE controller on ali15x3 chipset, which
causes all kinds of stability problems. (see dmesg)
Version-Release number of selected component (if applicable):
Use the computer for a while.
X (or even kernel) freezes completely from time to time.
System is stable.
The system works fine when run with acpi off, but since it is a laptop (HP
Omnibook vt6200), having no cpu frequency scaling eats up the battery pretty
This is a know bug, see

reported it here so that others may find it, too.

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Sorry, the laptop wasn't really usable in its current state, so I installed
FreeBSD on it.
Maybe monitor lkml and see if the bug gets fixed? Or just close as CANTFIX?
Okay Atte. Thanks for filing anyway.
