Additional affected server: sigma — matching scheduled-fstrim panic on
2026-10-05
This is a second physical server, distinct from zephir in the original
report. Its saved panic has the same IRQ stack-overflow signature and
the same sequence of resolved IRQ call-frame function names as zephir's
manual reproduction, ignoring offsets and uncertain (`?`) frames.
Timeline (UTC, 2026-10-05):
- 00:52:37: the weekly fstrim.timer triggered and the journal records “Starting
fstrim.service - Discard unused blocks on filesystems from /etc/fstab...”. This
is the last surviving entry in the previous boot's journal; no successful
completion is recorded for that invocation.
- 00:53:29: timestamp of the preserved ERST fragments, 52 seconds after the
service start. This is an archived record timestamp, not an exact wall-clock
timestamp for the initial fault.
- 00:55:11: first journal entry in the next boot.
- 05:16:44–05:17:38: a later manual start of fstrim.service completed
successfully. It reported trimming /boot/efi, /boot, /storage (820.8 GiB), and
/ (128 GiB).
Important kernel-version distinction: the crashing boot was running
7.0.0-31-generic #31-Ubuntu (Ubuntu 7.0.0-31.31-generic 7.0.14). The
subsequent boot and successful manual test ran 7.0.0-34-generic
#34-Ubuntu. The previous boot's kernel log and the panic agree on -31;
the collected uname and boot history establish -34 for the later test.
Therefore the manual test is not a successful retest of the same kernel.
It also does not establish that -34 fixes this bug: the original zephir
report already includes crashes on -34.
Panic details:
- BUG: IRQ stack guard page was hit at ffffcc4dc0318ff8 (stack is
ffffcc4dc0319000..ffffcc4dc031d000).
- RIP: bdev_end_io_acct+0x6e/0x280.
- Kernel panic - not syncing: Fatal exception in interrupt.
- First fault at uptime 2018287.532103 seconds; panic at 2018288.097594 seconds.
- The first panic's IRQ trace has 67 __dm_io_complete, 67 dm_io_dec_pending, 67
clone_endio, and 69 bio_endio resolved frames, excluding duplicate Oops copies.
These counts match zephir.
- The lower completion path includes md_end_clone_io, raid_end_bio_io [raid1],
r1_bio_write_done.part.0 [raid1], raid1_end_write_request [raid1],
blk_mq_end_request_batch, nvme_pci_complete_batch [nvme], and nvme_irq [nvme].
System details and limitations:
- Ubuntu 26.04.1 LTS, amd64.
- eSync Super4U / Supermicro X13SAE-F, BIOS 3.3 (DMI date 06/24/2024); Intel
Core i9-12900K.
- Unlike zephir's untainted traces, sigma's panic is tainted P/O. Its boot log
explicitly reports the proprietary/out-of-tree NVIDIA module taint, and its
panic module list includes nvidia, nvidia_modeset, nvidia_drm, and nvidia_uvm.
These are relevant differences, not an established cause.
- Boot parameters include mitigations=off and panic=30; the selected boot log
contains the full command line.
- Boot logs show XFS on dm-6 and dm-13. The trace confirms the
device-mapper/RAID1/NVMe completion path, but a full dmsetup/LVM topology
listing was not included in this collection.
- The timer listing collected at 05:21 UTC still schedules fstrim.timer for
2026-10-12. Disabling it has been recommended; this collection does not
establish that it has since been disabled.
Attachments prepared for this update:
- sigma-fstrim-crash-trace.txt: complete first panic section, with part headers
and the duplicate Oops copy omitted; the original log lines are retained.
- sigma-bug-2169515-evidence.tar.gz: that trace, trim history, system/timer
configuration, relevant boot boundaries and selected previous-boot kernel
messages, plus provenance and checksums.
Original source archive retained: monday-crash.zzGEvm.tar.gz; pstore
record 7692980532505739274. This is additional evidence of a matching
failure during scheduled trimming. The precise underlying defect remains
unconfirmed.
