Title:
Processes blocked indefinitely in kernel: queue_log_writer+0x8c/0xd0
[reiserfs]
Status in linux package in Ubuntu:
Invalid
Bug description:
Reiserfs seems to have triggered freezes in several applications. They
are hard kernel level freezes (the process is blocked in the kernel).
This happened while I was away from the machine. Chromium, GNOME
Terminal and other basic Unity/Gnome apps were sitting idle. The
problem went away once I rebooted the machine. Reiserfs is used only
for my /home.
Attached is a kernel log that shows stack traces from the blocked
processes. But here is the interesting bit, ubuntuone-syncd and
chromium-browser had identical stack traces in the kernel freeze:
