Comment # 3 on bug 107375 from Paul Menzel

With v4.19-rc4-22-gad3273d5f1b9 (Merge tag 'ext4_for_linus_stable' of
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4) this now got worse,
and `amdgpu_device_ip_resume_phase2()` now takes 1.166 s.

`psp_np_fw_load()` takes 868.190 ms, and `dm_resume()` 178.380 ms.

It’d be great, if you could talk to the PSP firmware team, and also document,
if you can reproduce this.
