Hi,
I invoked software suspend with kernel 2.5.27 and get the following messages
from kernel:
Stopping tasks: ========================
stopping tasks failed (3 tasks remaining)
Suspend failed: Not all processes stopped!
Restarting tasks...<6> Strange, jfsIO not stopped
Strange, jfsCommit not stopped
Strange, jfsSync not stopped
done
Afterwards, I have full cpu utilization of the JFS kernel threads:

Mem: 126284K total, 97112K used, 29172K free, 0K buffers

I used to have problems with JFS anyway when unpacking big tar archives. The
the system gives an oops and locks up a short while after. The process it is
stuck in is JFSCommit.
I tried latest 2.4 and 2.5, always had the same problems. Strangely JFS
causes no problems at all when I uses the kernel my partitions were
formatted with. That is slackware kernel 2.4.18, jfs 1.0.18. Any kernel
later with jfs versions higher causes these JFSCommit freezes.
I will send an oops report of JFS later.
Regards,
Axel Siebenwirth
