Public bug reported:
i'm reporting this here because the problem was solved when running a
5.15 or 5.19 kernel, but reappeared when trying 6.2 again. i therefore
assume it might indeed point to a bug in the 6.2 kernel.
i often do larger file transfers on a desktop machine currently running
kubuntu 22.04.3 LTS with kubuntu backports and HWE kernel (low latency
for audio recordings). a single recording session can be 20 GB, i'm
rsyncing it from one partition to another on the same system. since a
few weeks, i'm running into file system issues during these transfers:
[15104.146766] Aborting journal on device md6-8.
[15104.166906] EXT4-fs error (device md6): ext4_journal_check_start:83: comm
rsync: Detected aborted journal
[15104.695117] journal_release_journal_head: freeing b_frozen_data
the device is then re-mounted read-only an rsync aborts. this happens
out of nowhere after a few gigabytes of data and is not limited to a
specific RAID device. i ran a complete long test with smartmontools on
both disks, it didn't find any issues. after such an incident, e2fsck
fixes the number of free inodes and blocks and it can be used again,
until the next large file transfer.
i ran memcheck86 and indeed found some tests were failing with one of my
RAM modules, but removing the module didn't solve the issue. what
actually solved it was using an older kernel version. i first tried 5.15
and am now using 5.19, i don't get read-only filesystems on large
transfers with any of both.
some additional info that might be relevant:
- the filesystems are all on RAID 1 devices, ext4 and use fscrypt
- the hardware on the affected machine is pretty dated (ASUS Z97-K mainboard,
intel i5-4460 CPU 3.20 GHz, 8GB DDR3 RAM, NVIDIA GeForce GT 610), except for
the hard drives
