I tried to update the BIOS from BIOS where I could see version of BIOS
is from August this year. I was not able to confirm there is newer
version of BIOS available. I suppose I could try to write email to HP
support to confirm that information.

Title:
low CPU frequency after wake up AMD Ryzen

Status in linux package in Ubuntu:
New

Bug description:
After wake up I can see at least once a week issue with CPU frequency
not going up. When running:

$ watch lscpu -e=CPU,MHZ

standard output looks like:

CPU MHZ
0 400.0000
1 1383.2480
2 400.0000
3 400.0000
4 400.0000
5 2699.7561
6 1288.0500
7 400.0000
8 400.0000
9 400.0000
10 400.0000
11 400.0000
12 3244.0720
13 400.0000
14 400.0000
15 1295.9050

while when the issue occurs, I can't see 600 Mhz or higher values in
the same graph. Which also means that response time of computer is
much lower and everything feels lazy.

Restart fixes the issue or plug power cable off and in again.

My CPU is AMD Ryzen™ 7 PRO 7840HS w/ Radeon™ 780M Graphics × 16
My kernel version: 6.8.0-48-generic #48-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 27 14:04:52 UTC 2024
OS version: Ubuntu 24.04.1 LTS
My laptop: HP ZBook Firefly 14 inch G10 A Mobile Workstation PC

I know about one more person with same machine type with the issue and
there is also this question on askubuntu which says there is third
person with this issue.
