https://bugzilla.kernel.org/show_bug.cgi?id=43292 --- Comment #8 from Jan Kara <jack@xxxxxxx> 2012-05-30 13:33:29 --- Hum, it looks exactly the same like the previous attempt. I'm starting to suspect some problem with plugging or bio list handling. Since I can see you can trigger the lockup pretty quickly, can you gather blktrace data for me? The filesystem is on some device mapper device so you'll need to run something like: blktrace -d /dev/dm-2 -d /dev/sd? ... where you include all scsi disks compounding the dm device. And then just tar.gz the created files after the lockup happens and attach them here. Hopefully we'll be able to see where the read got stuck.
