@Alex
Well it's officially released now. It's up to you to install the patch.
:-)
I think someone needs to verify the patch as soon as it's in -proposed
state. Without verification it will be dropped from the source code. (
-> no official fix will be provided in -updates.)
Normally it's not the case if multiple users are affected. Someone just
needs to do the verification work.
Title:
CIFS stopped working/is unstable with kernel update to 5.15.0-102.112
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Jammy:
Fix Released
Bug description:
Hi,
updated some Ubuntu 22.04 systems to lastest available state this
morning, which caused CIFS mounts (from various fileservers) to stop
working. Kernel was updated to version 5.15.0-102-generic.
I can mount the shares without problems (mount -t cifs), but then, df for example tells me: df: /mnt: Resource temporarily unavailable.
I'm able to list and browse all the files, but accessing them (even readonly) is very unstable. Sometimes it works and sometimes it just gives me i/o errors.
Switching back to 5.15.0-101-generic or 5.15.0-100-generic solves the
problem and everything works again as expected.
Seems like some bug has been implemented in 5.15.0-102-generic...
To reproduce the problem, I started a while loop on one server to
write to some file on a specific mounted CIFS share and read it from
another one
Thanks a lot !

While doing this, both servers tell me, the resource is unavailable
