Bug Description
3 Ubuntu VMs using the latest kernel all show the same issue when using an fscrypted folder on CephFS.
No problems occur when the fscrypted folder is not decrypted but after decryption dmesg output shows what looks like a kernel oops and the machines are partially locking up (no access to the Ceph area or fscrypted area) or fully locking up requiring a hard reset.
It is unclear to me whether this is also potentially causing data corruption so probably needs triage before this really ruins someone's day/s.
Reverting to booting the previous kernel (6.5.0-41-generic) fixes the problem, so it seems related to 6.5.0-44-generic only thus far.
I have attached dmesg output.
