[Bug 2071523] Re: Ubuntu 24.04 LTS freezes on Thinkpad T510 with kernel 6.8.0-36-generic

[Christian Weisel]

Retested today after upgrade to kernel 6.8.0-38-generic.

Same behavior as before. System is freezing after some user activity while logging in.
Sometimes login finishes but then system freezes once there is some user activity.

Also testest with additional kernel parameter "nomodeset" as it seemed to me that his is related to i915 GPU. System is working stable but with not optimal screen resolution and a lot of dimesg warnings like:
intel ips 0000:00:1f.6: failed to disable graphics turbo

Any idea how the behavior like with kernel 6.5 like in Ubuntu 23.10 can
be restored also with 6.8 kernel?

Bug description:
  Upgrading my Thinkpad T510 from Kubuntu 23.10 to 24.10 worked fine but the system freezes after some minmal activity with the kernel 6.8.0-36-generic.
  No chance to check any log files or check for other issues. System freezes completly.

  Booting with advanced options and choosing the old 23.20 kernel
  (version 6.5.0-28-generic) works perfectly fine.
