'fsfreeze -u /' (or whatever filesystem these tasks are hanging on) should fix the problem. Autobuild is a likely candidate - see bug 805732. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There must be some userspace app that asked kernel to freeze the filesystem and so it did. It is a userspace problem. If this is reproducible at all for you, you can instrument 'fsfreeze' binary (or directly kernel freeze_super() function using ftrace) to find out who exactly called it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
