Thank you for taking the time to open this bug report. I have looked into the differences between the two kernels 6.5.0-41-generic, and 6.5.0-44-generic that have changes related to ceph.
There are three changes: https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/mantic/commit/?id=451adb3c51e01d0e207822d613a192177e3c9810 https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/mantic/commit/?id=5890896daa148cab30828f7a81042132c7b3e094 https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/mantic/commit/?id=11037a10f75996d0d3f221986cc2b7e9269cfc2d The third commit here is the more interesting one. It is a backport of 8e46a2d068c92a905d01cbb018b00d66991585ab. And if we look at the upstream we find this commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=321e3c3de53c7530cd518219d01f04e7e32a9d23 which addresses fixes an issue introduced with this commit. This patch is already in the noble: https://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/noble/commit/net/ceph?id=321e3c3de53c7530cd518219d01f04e7e32a9d23 As the 6.5 kernels are no longer being updated, and are end of life, we can't fix it in 6.5, and it seems to already be fixed in 6.8. ** Changed in: linux-signed-hwe-6.5 (Ubuntu) Assignee: (unassigned) => Philip Cox (philcox) ** Changed in: linux-signed-hwe-6.8 (Ubuntu) Assignee: (unassigned) => Philip Cox (philcox) ** Changed in: linux-signed-hwe-6.5 (Ubuntu) Status: New => Won't Fix ** Changed in: linux-signed-hwe-6.8 (Ubuntu) Status: New => Invalid ** Changed in: kernel Status: New => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed-hwe-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2073679 Title: Kernel linux-image-6.5.0-44-generic appears to have issues with fscrypt running on CephFS backend. Status in linux: Fix Released Status in linux-signed-hwe-6.5 package in Ubuntu: Won't Fix Status in linux-signed-hwe-6.8 package in Ubuntu: Invalid 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.
