Description Michal Hlavac 2023-07-25 06:40:25 UTC

Hi,

After upgrading to kernel 6.4.x I experienced these problems:
1. When notebook has disconnected power, it boot only to console (no X)
2. When power is disconnected, notebook does not suspend to RAM.

dmesg log when I disconnect power is:
>> [Ne júl 23 11:35:28 2023] ata2: SATA link down (SStatus 4 SControl 300)

Then I found same problem described here:
https://bbs.archlinux.org/viewtopic.php?id=286976

And as workaround I disabled bumblebee service and now it works.

Comment 1 Takashi Iwai 2023-07-25 14:07:17 UTC

Could you report it to the upstream?  e.g. bugzilla.kernel.org at start.
Although bbswitch is a downstream stuff, this kind of regression shouldn't happen.

Comment 2 Takashi Iwai 2023-07-30 08:40:24 UTC

And, it's a regression of 6.4.x, i.e. when you boot 6.3.x, everything still works as is?

Comment 3 Michal Hlavac 2023-08-01 10:54:39 UTC

Hi Takashi,

thanks for reply. Is there any easy way how to reproduce this on 6.3.x kernel on Tumbleweed? thanks

Comment 4 Takashi Iwai 2023-08-01 11:25:40 UTC

Just boot 6.3.x kernel :)
I guess 6.3.x is still available in OBS TW history repo
  http://download.opensuse.org/history/
If not, you can find my OBS archive repos, e.g. OBS home:tiwai:kernel:6.3.

But if you need a KMP, it can be problematic.  You need to build KMP locally.

Comment 5 Michal Hlavac 2023-08-02 19:34:13 UTC

Thanks Takashi for the history repos link. I didn't know they existed.

installed packages:
sudo zypper in --oldpackage kernel-default-6.3.9-1.1 bbswitch-kmp-default-0.8_k6.3.9_1-13.31 bbswitch-0.8-13.31

cat /proc/acpi/bbswitch
OFF

KDE plasma started when I booted to 6.3.9 with a disconnected power adapter.

Only the text console started when I booted to 6.4.6 with a disconnected power adapter.

So I think I can confirm that the 6.3.x kernel works as expected.

Comment 6 Takashi Iwai 2023-08-03 05:38:52 UTC

Thanks, it's clearer now.  Have you already reported it to the upstream?
You can use bugzilla.kernel.org, for example.

Comment 7 Michal Hlavac 2023-08-03 05:51:13 UTC

Yes, upstream bug is https://bugzilla.kernel.org/show_bug.cgi?id=217705

Comment 8 Takashi Iwai 2023-10-24 13:54:07 UTC

This seems to be an issue of rtsx ASPM stuff.  The upstream contained the fix.
