--- Comment #14 from Jan Kara (jack@...e.cz) ---
Well, the reason for jbd2 thread staying for long in
jbd2_journal_commit_transaction() can be simply a busy disk. So without more
details it's difficult to tell whether you are really facing the same issue. So
which processes are hung, does the hang eventually resolve itself or is reboot
needed? Please provide sysrq-w output from dmesg when the system is hung.
