Zach seemed to think that this is already fixed - I am not in a
position to test it immediately so if we know what fixed this - can be
closed. I'll report back once I get a chance to test latest git.
Parag, thanks. I reproduced this bug with your kernel config on
2.6.23-rc3 and verified it does not happen on latest git. I inspected
memory after the crash and determined the problem was patching of
instructions went awry. Chris in the meantime fixed a bug with patching
instructions, and the change from 100% apocalyptic failure to 100%
unequivocal success has convinced me that was the same bug.
