Pop!_OS: Boot Freeze / Very Slow Boot After Kernel Update

[hirezadehghani]

After updating Pop!_OS, my notebook no longer wakes up correctly after suspension. The screen remains black and I can restart it with alt+magikkey+RESUB.

This issue right after a system update. Reverting to an older kernel (6.16.3-76061603-generic) resolves the issue completely.

System Information
Pop!_OS version: 22.04 LTS
Kernel version that fails: 6.17.4-76061704-generic
Kernel version that works: 6.16.3-76061603-generic
Graphics: dual GPU (integrated intel + nvidia)

Output of uname -a (on affected kernel):
Linux pop-os 6.17.4-76061704-generic

Steps to Reproduce
Boot into kernel 6.17.4-76061704-generic
Screen remains black a - was blinking and boot was freeze but keyboard input was working.

What I've Tried
1- systemd-analyze blame showed:
plymouth-quit-wait.service delaying boot.
Snap-related services slow.
NVIDIA-related services present.

2- Investigated Plymouth (boot splash)
Verified Plymouth is included in initramfs:
lsinitramfs /boot/initrd.img-$(uname -r) | grep plymouth

3-3. Checked installed kernels
Confirmed multiple kernels installed.
Only the old kernel boots normally.

4. Verified NVIDIA driver installation
   Confirmed all NVIDIA 580 packages were installed.
   System is running in integrated (Intel-only) mode.

5. Identified possible incorrect kernel–driver interaction
   Hybrid GPU laptop using integrated mode may have conflicts with:
   NVIDIA DKMS modules
   New kernel version
   Plymouth renderer (framebuffer/DRM)

Please let me know if logs or further testing are needed. I'm happy to help.

Similar problems here too.
Since the kernel update to v6.17.4, several NVMe timeouts occur during booting, causing a boot time of ~5 minutes.
In some cases, booting fails completely (>15 minutes) or a kernel panic occurs.

Hardware:

• NVMe: Micron_2450_MTFDKBA1T0TFK
• Firmware: V5MA010
• System: Pop!_OS 22.04 LTS

Problem:
Kernel 6.17.4 causes NVMe timeouts during boot:
nvme nvme0: I/O tag XXX timeout, completion polled

System boot takes ~5 minutes or fails completely.
With kernel 6.16.3 everything works normally.

Features tested/disabled without success:

• nvme.nohmb=1
• nvme_core.default_ps_max_latency_us=0
• pcie_aspm=off
• nvme.noacpi=1
• nvme.force=1

Filesystem:

• LUKS encrypted root partition

Old kernel (6.16.3-76061603-generic) boots instantly without problems.

Please advise if additional logs or bisect information is needed.
