Can you check /sys/block/xxx/stat or something to make sure there is
no outstanding IO request?
It seems to be no response from the lower layer...
Once the system locks up I dont have any ability to do anything.

Yeah, got sysrq working today. If you can point me at the patch I
happy to apply it and get data.
