https://bugzilla.kernel.org/show_bug.cgi?id=202879 --- Comment #7 from Jungyeon (jungyeon@xxxxxxxxxx) --- Created attachment 281825 --> https://bugzilla.kernel.org/attachment.cgi?id=281825&action=edit another test set I'm attaching another error case what shows the same failure. This includes much less system call (15 calls) so I hope this can help to figure out this bug. - Reproduce ./lkl/tools/lkl/ext4-combined -t ext4 -i tmp.img -p min_11.c.raw -v (min_11.c shows it's internal programs) - Call stack [ 0.040743] BUG: failure at fs/jbd2/journal.c:2538/__journal_remove_journal_head()!
