reiserfs's fail to umount during shutdown after kernel upgrade to 2.4.3-12
Last modified: 2007-04-18 12:37:01 EDT
Description of Problem:
Shutdown/Reboot hang on "Unmounting file systems". Keyboard is still
responsive (enter outputs line break to stdout), but shutdown just halts
there, and no file systems are umounted.
Shutdown/Reboot IS successful with origonal kernel 2.4.2-2.
Upgrade and reinstalls of 2.4.3-12 kernel from rpm cause problem to repeat.
rpm -ivh --force of kernel 2.4.2-2 (and headers) make problem go away
This is on a Dell Latitue CPi D266XT laptop with 96mb ram, 10gig hdd (which
is non-standard. Bios only reports 8gig, linux uses full drive), 266

Version-Release number of selected component (if applicable): 2.4.3-12
I don't have another machine I'm able to test this on at this time, but on
this machine I have tested re-installing kernel-2.4.3-12 and headers adn
source and docs, and it causes the same problems. Reverting to 2.4.3-12
Steps to Reproduce:
Everything else is functioning normally with new kernel. System runs fine
until shutdown attempts (which would actually be fine by me if this wasn't
The hard drive is non-standard for this laptop and is above max size. I
doubt this has anything to do with it, but it might. The origonal hard
drive is completely dead, or I'd swap it back in and test with it.
Reverting to kernel 2.4.2-2 fixes the problem, and the bugs on it don't
seem to be too bad, so it's an acceptable solution for me for now.
There is a known issue in 2.4.3-12 wrt reiserfs unmounting;
I've put up a fixed 2.4.3 kernel at
for this; might be worth a try.
(sometimes some architectures are missing, I don't have too much quota but if
one is missing just ask and I'll put it up somehow)
Thank you! 2.4.3-18 fixed the problem.
When are we going to get an official 'update' to the kernel. RH7.1 kernels are
pretty old now.
