Attach WinDbg and run !analyze -v when the driver crash. Publish the
output here.

What was the last call from your driver? Put debug messages in all
dispatch functions and see which was the last before the hang.
In general, you don't need to do something special in StopAdapter.

Hitesh,
To additional to my previous advise you could run
!running which will show all currently running threads
and !stack 2 which shows full stack of running threads. There is good
post in OSR now which called "System lockup" and Scott Noone gave some
advises on similar to your situation. I would also suggest to install
check build version of partition manager, disk.sys and
scsiport(storport.sys whichever you use) and enable debug messages
from Windows kernel components by running ed !kd_WIN2000_Mask 0xffff.
You may see the last calls of storage stack components started from
partmng and finished your driver.
