ARM kernel snapshots - 2.6.31

I've built kernel snapshots for armel based on 2.6.31.1.  If your
device has a recovery mechanism or a serial console, feel free to test
them on your favourite ARM machine and report any problems you
encounter to this list.

You can find the kernel packages at
http://people.debian.org/~tbm/armel/kernel/r14304/

I still get these dmesg WARNINGs on the sheevaplug.
Does not seem to be related to load or anything. Happens about once an hour.
As before, they don't seem to have any observable negative impact on anything
except for spamming the dmesg log... :)

I also have these kernel WARNINGs, not in debian, but using the kernel
I build in my own with gcc 4.3.4. At least with 2.6.31.

The patch at the end of http://patchwork.kernel.org/patch/40871/
should fix this issue.  Now I just need to find out why this patch has
never made it into upstream.

Does these new kernel snapshots have already implemented the dma-patch
for the Thecus N2100 ?

No, that patch is not maintained and won't be put into the Debian
package.  Steve Langasek seems to have modern kernels with the patch,
though, so maybe he can publish them somewhere.

Andrew Morton will make sure the fix for this will land in 2.6.32 [1] and
I just commited the patch to Debian's 2.6.31.

Thanks for reporting this issue.
