2.6.0-test9-mm4: page allocation failure. order 3, mode 0x20

[Jurriaan]

After several runs of cdda2wav I get this message:

Nov 21 07:03:34 middle kernel: cdda2wav: page allocation failure. order:3, mode:0x20

I ran cdda2wav a lot more under 2.9.0-test9-mm3 and didn't see this
message.

Kind regards,

Are you sure you were running -mm4 and not Linus's kernel?  -mm has a tweak
for this, and it was present in -mm4.

It would help to add this patch; maybe the allocation is coming from
somewhere else.

I was running -mm4, sure.

Unfortunately, I've been unable to reproduce it, even when running the
same programs as I remembered running at that time.

ELF is the first rock group that Ronnie James Dio performed with back in 
the early 1970's.  In constrast, a.out is a misspelling	 of the French word 
for the month of August.  What the two have in common is beyond me, but 
Linux users seem to use the two words together.
