6.7 regression: platform 4809c000.mmc: deferred probe pending

6.7 regression: platform 4809c000.mmc: deferred probe pending

[Andreas Schwab]

I'm getting these messages on the PandaBoard since 6.7:

[   29.285522][  T156] platform 4809c000.mmc: deferred probe pending
[   29.291748][  T156] platform 4a0ab000.usb_otg_hs: deferred probe pending

As a result, the SD card is not found.
Any idea what's going on here?

Hi, Thorsten here, the Linux kernel's regression tracker.

Thanks for the report.Added the omap list and the omap mmc maintainer;
the root of the problem might be somewhere else, but maybe we get some
help from there.

Haven't heard of anything like that. Unless some developer replies with
some idea in a day or two I guess you will have to bisect the problem.

[TLDR: I'm adding this report to the list of tracked Linux kernel
regressions; the text you find below is based on a few templates
paragraphs you might have encountered already in similar form.
See link in footer if these mails annoy you.]

Anyway, to be sure the issue doesn't fall through the cracks unnoticed,
I'm adding it to regzbot, the Linux kernel regression tracking bot:

#regzbot ^introduced v6.6..v6.7
#regzbot title arm: omap: platform 4809c000.mmc: deferred probe pending
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Developers: When fixing the issue, remember to add 'Link:' tags pointing
to the report (the parent of this mail). See page linked in footer for
details.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

There was a regression recently with the PMIC which would cause NFSroot
on devices to keep working but may have affected MMC. Please check that
commit 7a29fa05aeca ("mfd: twl6030-irq: Revert to use of_match_device()")
is applied. If that does not help, then git bisect is the way to go.

Regards,

Tony

That commit hasn't hit stable yet.  Maybe it's because it references a
non-existant commit id (1e0c866887f4 instead of 830fafce06e6).

Yeah, our tools can't do about a commit that does not have a cc: stable@
tag in it AND the only commit it does reference is not one actually in
the tree at all.

An impossible task for us here, please ask stable@vger.kernel.org to
take the commit if this is needed, and let us know how far back it
should go.

thanks,

greg k-h

Andreas, did commit 7a29fa05aeca solve the issue? If so please send
and email to the stable list.

To be explicit, does this need to be applied to the stable tree(s)?  If
so, please email stable@vger.kernel.org with the git id to do so.

Andreas, Tony afaics asked you to do that here:
https://lore.kernel.org/all/20240226113635.GX52537@atomide.com/

But unless I missed something nothing happened since then. Did it fall
through the cracks? Reminder, if that patch clearly applied to 6.7.y
then all that's afaics needed is a mail with a simple text along the
lines of "Greg, please pick up 7a29fa05aeca2c ("mfd: twl6030-irq: Revert
to use of_match_device()") for linux-6.7.y, it fixes a bug I ran into
and Tony is fine with it."

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
