Console output from Alt-SysReq-T during an unmount hang (17.03 KB, text/plain)

Description Dan Christian 2004-05-11 16:40:26 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.2)

Description of problem:
On shutdown/reboot, the system can wait forever during the "Unmounting
file systems" step of shutdown. I've left it waiting overnight, and it
never returns on its own.  Ctrl-Alt-Del will nudge it into rebooting.

The test system is a dual Xeon CPU with an AMI Megaraid RAID controller.

This happens about 1 in 10 times.

There is no apparent file system corruption or loss of data; but it
makes un-attended reboots problematic.

I'll attach a Magic-Sysrequest list of processes in a minute.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  Boot system
2.  Write a few thousand files
3.  Reboot

This shows up both with mount-2.11y and mount-2.12.
Comment 3 Dan Christian 2004-05-14 13:44:48 EDT
This stills happens in kernel 2.6.5-1.358
Comment 4 Dave Jones 2004-12-08 01:39:21 EST
any better in 2.6.9 update ?
Comment 5 Dave Jones 2005-04-16 00:02:32 EDT
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
