I know. The problem is that 2.5.53 cannot finish booting on the Alpha I have
here (IDE issues). While I can port the patch over, I'm not comfortable being
unable to test it at all.

What kind of Alpha? Got an oops/backtrace?

I probably can't reproduce it directly since my Alpha's diskless.

The machine in question is a DS10 Alphaserver (DP264 type chipset) using an
ALI M5229 rev c1 IDE controller (uses the ALI 15x3 driver). The stock 2.5.53
kernel panics at boot time because it can't find the root partition; when I
first reported the problem, one of the maintainers passed on a patch that
resolved some 2.5 IDE issues. With the patch in place, the boot process gets
farther along but occaisionally there will be a printout that hda lost an 
interrupt. I don't know how far it really gets, because I gave up after other
subsystems started reporting errors.

I haven't tried 2.5.54, either. I will shortly.

Is 2.4 really in bug-fix mode now? 2.4.19 and 2.4.20 were huge patches.

Thanks,
jasonp

Sounds like a job for the IDE crew, who appear to know there are
pending ali + Alpha issues.

[PATCH] page coloring for 2.4.20 kernel, version 2

[Jason Papadopoulos]

Version 2 of the page coloring patch is ready. This version includes 
support for non-power-of-two cache sizes, fixes the ia64 cache detection 
code (thanks due to Alex Williamson), and fixes a small initialization bug.

New patch available at

www.boo.net/~jasonp/page_color-2.4.20-20030114.patch

Thanks in advance,
