Hi Girish,
When running fsstress on an x86 machine, I hit the kernel oops below. The ext4-patch-queue is being tested including the journal checksum patches
I have mounted with -o delalloc,mballoc,data=writeback,journal_checksum
I did not get a chance to look in detail; but it looks like a journal issue. Do you know what the issue might be?
BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:
c118ba5d
*pdpt = 000000002560a001
*pde = 0000000000000000
