Bug 106796 – Mounted CIFS causes a freeze on reboot

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Danny Brain 2005-09-21 07:36:42 UTC]

When I have mounted a CIFS (in this cause a Samba mount on a local box) and try
to reboot the shutdown process will freeze on "Unmounting network filesystems ..".
This will not respond to anything, and ends up in a hard reboot.
I've tried unmounting the CIFS, but it still seems to get the same result.

If I remember correctly this problem did not exist the first time I started
using CIFS.

Marked as critical due to the dirtying of my filesystem cause by the hard
reboot. Sorry if this was a wrong labelling.

Reproducible: Always
Steps to Reproduce:
1. Mount a Samba filesystem using CIFS.
2. shutdown -r now
3. Make your poor old filesystem dirty :\

Actual Results:  
System froze on "Unmounting network filesystems ..."

Expected Results:  
Thawed out after unmounting the network filesystems ;)

I'm not sure wether this is kernel or baselayout land, please reassign if needed.

[Comment 2 Danny Brain 2005-09-21 08:06:30 UTC]

If it helps at all I'm running: baselayout-1.11.13-r1
Can move to the latest 1.12.0_pre8-r2 for testing purposes if required
(currently have them hardmasked due to the initial instability).

[Comment 3 Daniel Drake (RETIRED) 2005-09-29 01:24:27 UTC]

Is this reproducable on the latest development kernel? (currently
vanilla-sources-2.6.14_rc2)

[Comment 4 Daniel Drake (RETIRED) 2005-10-10 08:47:18 UTC]

Please reopen after you test the latest development kernel

[Comment 5 Danny Brain 2005-10-10 08:51:44 UTC]

Sorry for the late response.
I'm fairly sure it's a baselayout issue, I upgraded to 1.12.* and no longer had
these problems.
Of course this lead me to other annoying baselayout issues when mounting
filesystems, but oh well.

I'll leave it closed untill I get time to fiddle with development kernels, just
in case.
