I have gone through 3 unclean shutdowns so far - this time on Ubuntu
Karmic Release, today's -git and this patch.
Nothing odd to report.

[ Goes and crashes it again - comes back clean! ]

Since literally all of my previous attempts always resulted in
problems - something seems to have improved although there is no way
to tell if this is going to last long or that if it was Aneesh's patch
alone that improved things as last time i tried this I ended up
reinstalling and I switched to Karmic from Jaunty and I did not test
mainline for few days.

Any rate, I will let everyone know if I see anything different.

Thanks
Parag
