Comment 1 sander44 2024-05-19 17:58:44 UTC 
Maybe this commits cause issue:

210a03c9d51aa0e6e6f06980116e3256da8d4c48 - fs: claw back a few FMODE_* bits
3fed24fffc76dd1a8105db558e98bc8355d60379 - xfs: Replace xfs_isilocked with xfs_assert_ilocked
Comment 2 Mike Lothian 2024-05-21 06:48:28 UTC 
I've seen this without xfs on my machine, the journalctl was corrupted though

I'll try and reproduce
Comment 3 The Linux kernel's regression tracker (Thorsten Leemhuis) 2024-06-12 13:05:22 UTC 
What happened to this? Was this resolved, or is this still a problem?
Comment 4 Mike Lothian 2024-06-14 16:36:49 UTC 
It used to happen when I was compiling chromium in a ramdisk, it didn't happen with 6.10-rc3 though, so maybe its sorted
