https://bugzilla.kernel.org/show_bug.cgi?id=21092 Summary: Kernel 2.6.36 Bug during quotaon on reiserfs Product: File System Version: 2.5 Kernel Version: 2.6.36 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ReiserFS AssignedTo: reiserfs-devel@xxxxxxxxxxxxxxx ReportedBy: markus.gapp@xxxxxxx Regression: Yes I get this bug during boot at enabling usrquta for a reiser(3)fs since 2.6.36. The kernel is a x86_64 smp. The reiserfs reisdes on a dm raid level 5. The same setup worked with kernel version 2.6.35.7, of course there was no other configuratrion change between 2.6.35.7 and 2.6.36.

Any susequent try to enable quota result in a stalled quotaon command without any output on console or dmesg.
