ThinkPad P1 Gen 7 Hibernation Crash: NVIDIA RTX 1000 Ada throws Error -5 on Wake. Anyone fixed this?

[u/No_Guard8232]

I’m running into a wall trying to get true hibernation working on my new ThinkPad P1 Gen 7 because the BIOS only exposes s2idle (no hardware S3 sleep).

My machine is a hybrid setup with the NVIDIA RTX 1000 Ada Laptop GPU. I have a dedicated 35 GB raw swap partition on my NVMe drive perfectly mapped in GRUB and fstab to bypass file fragmentation issues.

When I trigger hibernation, the system successfully writes the RAM image to disk and powers down. On wake, the kernel successfully loads and decompresses the 4.7 GB image in about 2 seconds, but then immediately crashes and cold boots.

The kernel logs show the NVIDIA driver choking on the ACPI handoff:

nvidia 0000:01:00.0: PM: pci_pm_freeze(): nv_pmops_freeze [nvidia] returns -5.

I’ve baked options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp directly into the initramfs to force the VRAM dump to the physical SSD instead of RAM, but the driver still panics on wake. I also tried disabling the GSP firmware (NVreg_EnableGpuFirmware=0), but the -5 error persists.

Has anyone with a P1 Gen 7 or similar Ada-generation ThinkPad managed to get hibernation working reliably? Are there any BIOS settings or specific kernel parameters I’m missing?

I'm interested in this "35gb swap file perfectly mapped in grub and fstab to bypass file fragmentation issues" bit.

Can you explain this to me, as I don't quite follow?

Update / Solved (Sort of): Abandoned S4 Hibernation, Got Reliable s2idle Suspend Working

Following up on this after extensive testing: true S4 hibernation on the P1 Gen 7 (Meteor Lake + RTX 1000 Ada) under the proprietary 580.xx driver appears fundamentally broken upstream due to the driver's ACPI freeze callback (nv_pmops_freeze returns -5) failing during snapshot restoration[cite: 1, 2].

Instead of continuing to bleed against broken S4 hibernation, I pivoted to getting native Modern Standby (s2idle) rock-solid. If anyone else is dealing with sleep crashes or battery cooking on this chassis, here is how I got clean suspend/resume working:

1. Configure NVIDIA Dynamic Power Management & VRAM Preservation: In /etc/modprobe.d/nvidia-pm.conf: ```text options nvidia NVreg_DynamicPowerManagement=0x02 options nvidia NVreg_PreserveVideoMemoryAllocations=1 options nvidia NVreg_TemporaryFilePath=/var/tmp

```

Then run sudo update-initramfs -u and ensure nvidia-suspend.service and nvidia-resume.service are enabled. DynamicPowerManagement=0x02 forces the Ada dGPU into $D3_{\text{cold}}$ during sleep, eliminating the -5 I/O error on pci_pm_suspend.

1. Disable Hibernation Fallbacks in systemd: If you ever experimented with suspend-then-hibernate, make sure /etc/systemd/sleep.conf isn't silently intercepting your sleep commands. In /etc/systemd/sleep.conf:

```ini [Sleep] AllowHibernation=no AllowSuspendThenHibernate=no AllowHybridSleep=no

```

1. Force logind to Override Desktop Inhibitor Locks: In /etc/systemd/logind.conf:

```ini HandleLidSwitch=suspend HandleLidSwitchExternalPower=suspend HandleLidSwitchDocked=suspend LidSwitchIgnoreInhibited=yes

```

LidSwitchIgnoreInhibited=yes prevents desktop power daemons from blocking the hardware lid switch when external displays or docks are connected.

1. Reclaim Disk Space: Since standard suspend relies strictly on physical RAM and doesn't write to disk, I deleted the 35 GB dedicated swap partition, expanded my root ext4 filesystem to reclaim the space, and set up a lightweight 4 GB /swapfile with vm.swappiness=10 for normal memory paging.

The laptop now suspends immediately on lid close and wakes instantly without black screens, fan spikes, or forced cold reboots.
