Description Mark Dawson Butterworth 2022-01-18 14:39:00 CET

Description of problem:

CIFS has stopped working in recent kernels

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

Worked in 5.15.4, does not in 5.15.8 or 5.15.11. Suspect 5.15.7 may be where problem appeared - see https://bugs.mageia.org/show_bug.cgi?id=29784

How reproducible:

Whenever a CIFS volume is mounted

Steps to Reproduce:
1. Update, bringing a newer kernel into use
2. Attempt to mount a volume using CIFS
3. Get
mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

We see that the cifs module is not listed by lsmod:
lsmod | grep cifs
cifs_md4               16384  0
whereas it was with 5.14.4

This bug is probably the same as 29784 but I don't know how to make one bug refer to Cauldron and mga8.

Does 5.15.15-1 currently in Core Updates Testing work for you ?

Comment 2 Mark Dawson Butterworth 2022-01-18 16:32:48 CET

I've added Core Updates Testing to my list of sources but am not seeing 5.15.15 for some reason. Mirror issue?

Comment 3 Thomas Backlund 2022-01-18 16:43:34 CET

You can disable upates testing again, we are currently pushing 5.15.15 to normal updates

Thank you Mark for reporting the issue.

Thanks tmb for looking at this already.
Assigning to 'kernel' anyway.

Thanks Thomas, I can confirm the issue is fixed by 5.15.15. Sorry for the delay in responding.
