[Regression] Bug 216360 - No power to DVD drive

[Regression] Bug 216360 - No power to DVD drive

[Thorsten Leemhuis]

Hi Rafael. Could you help me out if you have a minute? I noticed
a regression report in bugzilla that nobody looked at yet. According to
the reporter the DVD drive's drawer of a small form factor system won't
open anymore since v5.16; the device is not even mentioned anymore in
the dmesg output. For details see:

https://bugzilla.kernel.org/show_bug.cgi?id=216360

Is that an ACPI problem and thus something you would handle? If not: in
which direction would you shove this?

Ciao, Thorsten

P.S.: To get this tracked:

#regzbot introduced: v5.15..v5.16
https://bugzilla.kernel.org/show_bug.cgi?id=216360
#regzbot ignore-activity

I honestly don't think so.

See https://bugzilla.kernel.org/show_bug.cgi?id=216360#c6

This issue is not reported against the mainline kernel, so it should
be handled by whoever provided the kernel the reporter is using.

Cheers!

Okay, already suspected that, thx.

Well, you for sure have a point. But well, from what I can tell the
Manjaro kernel is not heavily patched (see
https://gitlab.manjaro.org/packages/core/linux519; but the RT in the
kernel's name makes me suspicious). And from my experience quite a few
developer seem to be interested in regression reports from such kernels.
That's why I (for now) pick some of them up (I use my best judgement
here) and let the developers decide what to do with them.

In this case I just don't really know whom to ask to look into this. :-/

Anyway, Bruce, things really look a bit odd in this case. You should try
to seek help from Manjaro -- or check if it really happens with a
vanilla kernel(¹). If you do the latter, ideally consider to use "git
bisect" to find the change that is causing the different behavior. Then
we know for sure who needs to look into this.

Ciao, Thorsten

(¹) e.g. try a vanilla 5.15 kernel to see if your DVD works; use the
config from the Manjaro 5.15 kernel (consider running "make
localmodconfig" to reduce build times). Then compile a 5.16 vanilla
kernel with the config from your 5.15 kernel processed by 'make
olddefconfig'

Even so, it is not the mainline and that's what we work on.

Well, if you are absolutely sure that the third-party modifications
cannot be involved in the observed failure and you have the time to
assist the reporter, it is fine.  Otherwise you may not be helping.

Me neither.

Good advice.

This regression looks stalled (no reply from Bruce or maintainers), so
to clean up:

#regzbot inconclusive: no one cares the regression

[bruce]

All,

I have started work on trying to find which version of the kernel this 
bug first appeared. It is taking me some time to find how to do this 
(might be easy for you). But I have other priorities at present which 
mean I have not had the time to work on this. My present commitments end 
at the end of October and I expect to get back to this at that point.

Yes, I do care about this bug and I will get round to it but it on the 
equipment I have it is inconvenient, takes a long time for each build 
and stops me working on other things.

Regards,

Bruce Healey

Please don't top-post; reply inline with appropriate context instead.
This allows readers to follow and understand the conversation flow.

If you ever come into the specific culprit, let us know. In the
meantime, you can also try reproducing this regression on more
powerful device.

Thanks.
