Title:
XFS: kernel hangs multiple times in xlog_cil_force_lsn
Status in linux package in Ubuntu:
Expired
Bug description:
Ubuntu 14.04.3 LTS with Kernel 3.19.0-26-generic
One of our servers running rsnapshot and nfs-kernel-server on XFS partitions
crashed or hanged two sundays in a raw.
Kernel 3.19.0-26-generic hangs multiple times (same time) in
xlog_cil_force_lsn (XFS).
I assume this bug is not related with bug report 979498.
I had also this issue with kernel 3.16.0-46-generic or 3.13.0-57-generic but
I have
no log during the crash to determine which of the above kernel was running.
I switched to kernel 3.19.0-26-generic because 3.16.0-48-generic was not
working well with Intel Gigabit -- tx hang (bug 1492146)
