Tigran, do you have a new trace maybe?
I cross referenced the dump you sent to the
disassembled code and it seems like it hit NULL dereference on
size = fl->stripe_unit;
I'm going to commit this patch anyway but I want to
understand what else I missed...
Benny
The stack attached. Shall I compile the kernel with some debug options
for better debugging?
Tigran.
