Same issue on DEXP Ursus 7W with Linux 4.11rc1. 

dmesg is attached.

And here is my previous report that probably related: https://bugzilla.kernel.org/show_bug.cgi?id=115271

Possible workaround: https://github.com/burzumishi/linux-baytrail-flexx10/blob/master/kernel/patches/v4.8/0015-acpi_statically_assign_irq_in_reduced_mode.patch

Comment 3 Matthew Garrett 2017-03-09 17:26:02 UTC

Does this platform even have a legacy RTC?

Comment 4 RussianNeuroMancer 2017-03-09 17:42:10 UTC

How I can check this besides looking into /proc/driver/rtc?

Hi,

0015-acpi_statically_assign_irq_in_reduced_mode.patch

This patch seems to be the solution.

Comment 6 RussianNeuroMancer 2017-03-28 12:53:53 UTC

Matthew, could you please look into upstreaming this?

Comment 7 alan 2017-04-07 11:18:41 UTC

Hi,

The patch from Hans de Goede works. ;-)

Comment 8 alan 2017-05-04 10:59:57 UTC

Hi,

I will test the 4.11 final release to see if this bug is fixed.

Comment 9 alan 2017-05-11 13:12:18 UTC

Hi,

The problem is not solved in the 4.11 final release. A patch is still needed.

Comment 10 alan 2017-05-15 10:44:09 UTC

Hi,

I will see with the 4.12-rc1 release.

Comment 11 alan 2017-05-16 13:31:47 UTC

Hi,

I think the problem is solved and the patch is available in the 4.12-rc1 release. I used the 4.12-rc1 kernel sources from Hans de Goede and it works. :-)

Comment 12 alan 2017-06-07 12:22:09 UTC

Hi,

This bug report can be closed or not ?

Comment 13 RussianNeuroMancer 2017-06-09 08:53:42 UTC

If this issue is not reproducible on upstream 4.12 - then yes.

I can't test it because I doesn't have DEXP Ursus 7W anymore.

Comment 14 alan 2017-07-23 12:23:33 UTC

Hi,

it works like a charm on 4.13-rc1. 

I close that bug report.
