Hi,
I am using linux kernel 2.6.24, I get following crash when I unplug a SATA
disk while I/O is going on:

Can anybody please tell me the reason behind this crash? Is this a
known problem?
I found this http://lkml.indiana.edu/hypermail/linux/kernel/0610.3/index.html#1632
mail thread,
which is similar to this problem.
Please help.

Thanks,
