First off, thanks so much for tracking these, it can't be an easy job,
but one that is really needed.  Keep up the great work.

Last I heard was that Tino was going to try to do further testing, but
as he hasn't responded in a few weeks, I'd mark this one down to,
"unknown and unreproducable".  Unless someone else knows more?

thanks,

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.

Thanks

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.
