 Posted: Mon Jun 30, 2008 2:21 am Post subject: Kernel-2.6.25-r5 cifs crashing(solved by upgrade kernel) |
 |
|
Upgraded from Kernel-2.6.24 to 2.6.25 some days ago. Since then I can't mount Windows shares.
| Code: |
mount -t cifs //HAL2/Temp /mnt/usbdisk1/
|
Produces the following output in dmesg:

This machine runs Gentoo 64Bit with 26 BIT 2.6.25-gentoo-r5 kernel
Anybody any ideas ?
EDIT
Funny mistype:
This machine runs Gentoo 64Bit with 64 Bit 2.6.25-gentoo-r5 kernel

When you moved your .config from one kernel to the next, did you run make oldconfig? If not, you need to do so. Then you need to use either make xconfig or make menuconfig to make sure the options you desire are set.
Blessed be!

Sure I did that 
It's not my first kernel update and I'm using Gentoo since Profile "1.something".
SMBFS and CIFS as modules built.
If any more informations needed, please ask and I will post them,...
P.S. I think I will try and disable smbfs completely, maybe this helps

Then I'm out of ideas because mount.cifs works on this machine and my old Toshiba laptop whether I'm using kernel 2.6.22.19, or 2.6.25-gentoo-r4 or any versions in between. I did notice that there were warnings about smbfs being depricated, but I don't think that has anything to do with your problem.
Blessed be!

Tried to use smbfs. Mounting works fine but then umount command crashes
