https://bugzilla.kernel.org/show_bug.cgi?id=216566 Bug ID: 216566 Summary: [xfstests generic/648] BUG: unable to handle page fault, RIP: 0010:__xfs_dir3_data_check+0x171/0x700 [xfs] Product: File System Version: 2.5 Kernel Version: v6.1-rc0 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: XFS Assignee: filesystem_xfs@xxxxxxxxxxxxxxxxxxxxxx Reporter: zlang@xxxxxxxxxx Regression: No xfstests generic/648 hit kernel panic[1] on xfs with 64k directory block size (-n size=65536), before panic, there's a kernel assertion (not sure if it's related). It's reproducable, but not easy. Generally I reproduced it by loop running generic/648 on xfs (-n size=65536) hundreds of time. The last time I hit this panic on linux with HEAD= commit a6afa4199d3d038fbfdff5511f7523b0e30cb774 Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx> Date: Sat Oct 8 10:30:44 2022 -0700 Merge tag 'mailbox-v6.1' of git://git.linaro.org/landing-teams/working/fujitsu/integration [1] [ 397.108795] loop: Write error at byte offset 3952001024, length 4096.
