Okay. I tracked down the problem with git. Here is what is the submission that
causes the problem:

solaris linux-git # git bisect good
0916bd3ebb7cefdd0f432e8491abe24f4b5a101e is first bad commit
commit 0916bd3ebb7cefdd0f432e8491abe24f4b5a101e

[PATCH] Correct bound checking from the value returned from _PPC method.

The above commit seems to be the culprit behind this 2.6.19 regression, which is still present as of 2.6.21-rc3 (so it's not the earlier issue found by Ingo). Any ideas?

Thanks,
Daniel
