Comment 17 for bug 1971656

Hi, I experience the same problem with my Lenovo ThinkPad T14 Gen 2a (AMD Ryzen 7 PRO 5850U). Also, about 1 hour after waking up from suspend mode.

$ uname -a
Linux ThinkPad-T14-Gen-2a 5.15.0-41-generic #44-Ubuntu SMP Wed Jun 22 14:20:53 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

The last two lines are repeated until the machine is rebooted.

For now, I will try the options suggested in https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1971656/comments/13
