** Description changed:
Hi,
I see this issues since 4.15.0-32-generic, but I have this particular
smb/cifs setup for only a few weeks now, so it might after all by chance that I
started to see it with this particular kernel.
It seems that about any activity in regard to a mount that I had working
for a few days - mounted on monday, played music from it most of each
day, today is thursday - triggers this fault now.
- tab completion into the dir
- ls in target dir
- umount the mountpoint
Sometimes the tools do not immediately crash, but hang.
In that case they are on wchan "wait_for_response.isra.9"
The logs on the NAS (Synology DS418+) have no entries, the last is me
mounting it via smb/cifs.
Related FSTab entries are not too unusual other than making sure we have the
new safer version of the protocol used:
//10.7.0.231/music /mnt/nas/music cifs

alloc in such traces is always suspicious for OOM cases.
But there is plenty left (and most in cache as usual).

For testing of mainline kernels and such, I'm not yet sure how reproducible
this will be.
I hope it is a one-time issue, If it triggers again I'll report here to have
a feeling about reproducibility, but for now we have to assume that I can't
immediately trigger/test for it.
