Public bug reported:
After upgrading to Ubuntu 26.04, my Lenovo Legion laptop crashes when
entering suspend, especially when closing the lid. The crash also
appears reproducible via systemd-sleep / suspend, so this does not seem
to be only a lid-switch issue.
The kernel log shows the crash happens immediately after suspend begins:
PM: suspend entry (deep)
Filesystems sync: 0.008 seconds
jump_label: Fatal kernel bug, unexpected op at
nvkms_kthread_q_callback+0x8e/0x1a0 [nvidia_modeset]
kernel BUG at arch/x86/kernel/jump_label.c:73!
Oops: invalid opcode: 0000 [#1] SMP NOPTI
Relevant system information from the log:
Kernel: 7.0.0-15-generic #15-Ubuntu PREEMPT(lazy)
Hardware: LENOVO 83DG/LNVNB161216
BIOS: NMCN29WW 12/18/2024
Process: systemd-sleep
Sleep mode: deep
NVIDIA modules loaded: nvidia, nvidia_modeset, nvidia_drm, nvidia_uvm
The crash occurs in the proprietary NVIDIA kernel module path:
nvkms_kthread_q_callback+0x8e/0x1a0 [nvidia_modeset]
__jump_label_patch.cold+0x24/0x26
arch_jump_label_transform_queue+0x37/0x90
__jump_label_update+0x47/0x100
jump_label_update+0x5c/0x110
static_key_slow_inc_cpuslocked+0x53/0xa0
freeze_processes+0xd1/0xe0
enter_state+0xe0/0x610
pm_suspend+0x49/0x90
state_store+0x2e/0x60
What I expected to happen:
The laptop should suspend normally when I close the lid or run systemctl
suspend, and should resume normally when opened or woken.
What happened instead:
The system crashes / becomes unusable during suspend. The kernel reports a BUG
in arch/x86/kernel/jump_label.c while inside nvidia_modeset.
Steps to reproduce:
1. Boot Ubuntu 26.04 on this Lenovo Legion laptop.
2. Use the proprietary NVIDIA driver.
3. Trigger suspend, either by closing the lid or running:
systemctl suspend
4. The system crashes during suspend entry.
Additional observations:
- The log contains AppArmor audit messages from snap/Discord and snap-confine,
but these appear unrelated.
- The kernel is tainted due to proprietary/out-of-tree NVIDIA modules:
Tainted: P W OE
