Public bug reported:
# amdgpu/TTM: LRU bulk-move list corruption leads to fatal deref in
ttm_lru_bulk_move_tail and unrecoverable system hang (gfx1103)
## Summary
On an AMD Ryzen 5 8600G (Phoenix1 iGPU, gfx1103) the TTM LRU bulk-move list
becomes corrupted during amdgpu VM page-table teardown. The kernel warns but
continues. Roughly ten minutes later an unrelated process dereferences the
corrupted list and oopses **while holding the TTM LRU spinlock**, which is
therefore never released. Every subsequent GPU consumer blocks on that lock
forever, producing cascading soft lockups and an unrecoverable hang requiring
a hard reset.
## Version
- Ubuntu 26.04.1 LTS
- Kernel 7.0.0-30-generic #30-Ubuntu PREEMPT(lazy) x86_64
- Board: MSI PRO B650M-A WIFI (MS-7D77), BIOS 1.R3 08/05/2025
- CPU/iGPU: AMD Ryzen 5 8600G w/ Radeon 760M (Phoenix1, gfx1103, 1002:15bf rev
05)
- Second GPU present: Intel Arc B580 (8086:e20b, `xe` driver), compute only
- Displays are driven by the amdgpu iGPU (fb0 primary, HDMI-A-5)
## Impact
Total loss of the machine: display frozen, no VT switch, no SSH-able recovery
of GPU clients. Only a hard reset recovers. Filesystem journal replay follows
on next boot.
## Sequence
### Stage 1 — silent corruption (T+0, 09:06:27)
A `list_del` on a TTM LRU bulk-move sublist finds a corrupted `prev->next`,
during amdgpu page-table teardown driven by a Chrome `DRM_IOCTL_AMDGPU_GEM_VA`:
```
slab kmalloc-rnd-01-192 start ffff8db11b928480 pointer offset 64 size 192
list_del corruption. prev->next should be ffff8daba68d7700, but was
ffff8dab8858eee8. (prev=ffff8db11b9284c0)

```
The system continues running, now with a damaged list. A second identical
warning fires on CPU#4 in the same second.
### Stage 2 — fatal dereference (T+10min, 09:16:29)
An unrelated process walks the damaged list during command submission and
faults on a near-null pointer:
```
BUG: unable to handle page fault for address: 0000000000004008
#PF: supervisor write access in kernel mode
#PF: error_code(0x0002) - not-present page

amdgpu_cs_ioctl+0x235/0x390 [amdgpu]
drm_ioctl_kernel+0xb5/0x110
```
Critically, the faulting task dies inside the TTM LRU critical section:
```
note: lact[79654] exited with irqs disabled
note: lact[79654] exited with preempt_count 1
```
The LRU spinlock is leaked. Nothing ever releases it.
### Stage 3 — cascading deadlock (09:16:56 onward)
Every process that subsequently touches TTM spins on the leaked lock:
```
watchdog: BUG: soft lockup - CPU#5 stuck for 26s! [gnome-shell:11030]
watchdog: BUG: soft lockup - CPU#10 stuck for 27s! [KMS thread:11069]
watchdog: BUG: soft lockup - CPU#1 stuck for 22s! [chrome:33651]
```
with the expected signature, e.g.:
```

amdgpu_driver_open_kms+0x175/0x350 [amdgpu]
drm_open+0x77/0x120
```
Stall durations climb monotonically (22s → 152s) across gnome-shell, the KMS
thread, chrome and llama-server until the machine was hard reset at 09:19:36.
Note that stage 3 shows the bug is fatal to *any* new client: merely opening
`/dev/dri/card2` is enough to hang, because `amdgpu_driver_open_kms` allocates
page tables through the poisoned LRU.
## Analysis
The two processes named (`chrome`, `lact`) are incidental — they are simply the
busiest amdgpu clients. The corrupting write and the faulting read are ten
minutes and several processes apart, which points at a lifetime/ordering bug in
the bulk-move sublist rather than at any one caller. `amdgpu_vm_pt_free` calling
`ttm_bo_set_bulk_move(bo, NULL)` on a buffer whose bulk-move cursor is still
referenced elsewhere is the most likely candidate, i.e. a missing or mis-ordered
`ttm_lru_bulk_move_fini()`-style teardown.
The severity multiplier is that the oops happens under `spin_lock`, converting a
recoverable per-process oops into a whole-machine deadlock.
## Not hardware
- Zero machine-check exceptions and zero EDAC errors across the whole log window
- NVMe healthy; filesystem replayed clean on reboot
- No overclock or undervolt: `power_dpm_force_performance_level` is `auto`,
`pp_od_clk_voltage` at stock 800–2799 MHz, and the installed GPU utility
(LACT) had no clock or voltage profile applied
- 60 GiB RAM, no memory pressure at the time
## Reproducibility
Occurred once. The preceding four boots (spanning several days of identical
desktop + GPU-compute workload) contain zero instances of either the `list_del`
warning or the oops, so this is rare and timing-dependent rather than
deterministic. No known trigger.
## Attachments
- `amdgpu-ttm-traces.txt` — all three stages, full register state and module
list
- `prevboot-kernel.log` — complete `journalctl -b -1 -k` from the crashed boot
