regression v5.13..v5.15: USB hub stopped working -- DMAR fault when connected usb hub

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, this is your Linux kernel regression tracker.

I noticed a regression report in bugzilla.kernel.org that afaics nobody
acted upon since it was reported about a week ago. That's why I decided
to forward it to a few maintainers and mailing lists. To quote from
https://bugzilla.kernel.org/show_bug.cgi?id=215906 :

> Since kernel 5.15 (with kernel 5.13 I see no problem) I have a problem with my USB hub. The device stops working shortly after starting the system.
> In dmesg log I see DMAR fault on usb controller

See the ticket for details and further comments. According to the latest
one the problem is still present in 5.18-rc5.

Was this issue discussed or even addressed somewhere already? Or does
anyone at least have a good idea what might be causing this problem?
@reporter: If neither is the case, you most likely will need to perform
a bisection with git to identify the change causing the problem.

Anyway, could one of the kernel developers among the recipients please
help with this? BTW, I was unsure where to send this to the DMA/IOMMU
maintainers or the USB/xhci maintainers. I settled for the latter; I
apologize in advance if that was the wrong choice.

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

P.S.: As the Linux kernel's regression tracker I defsdal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.

P.P.S: to get this tracked by the the Linux kernel regression tracking bot:

#regzbot introduced: v5.13..v5.15
#regzbot from: Piotr Piórkowski <qba100@xxxxxxxxx>
#regzbot title: usb/dma/iommu/???: USB hub stopped working -- DMAR fault
when connected usb hub
#regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215906
#regzbot monitor:
https://lore.kernel.org/all/bug-215906-208809@xxxxxxxxxxxxxxxxxxxxxxxxx%2F/
-- 
Additional information about regzbot:

If you want to know more about regzbot, check out its web-interface, the
getting start guide, and the references documentation:

https://linux-regtracking.leemhuis.info/regzbot/
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md

The last two documents will explain how you can interact with regzbot
yourself if your want to.

Hint for reporters: when reporting a regression it's in your interest to
CC the regression list and tell regzbot about the issue, as that ensures
the regression makes it onto the radar of the Linux kernel's regression
tracker -- that's in your interest, as it ensures your report won't fall
through the cracks unnoticed.

Hint for developers: you normally don't need to care about regzbot once
it's involved. Fix the issue as you normally would, just remember to
include 'Link:' tag in the patch descriptions pointing to all reports
about the issue. This has been expected from developers even before
regzbot showed up for reasons explained in
'Documentation/process/submitting-patches.rst' and
'Documentation/process/5.Posting.rst'.
