snd_au8820 0000:01:04.0: BUG: , pos = 16388, buffer size = 16384, period size = 1024

[sudodus]

This bug does *not* affect precise and *not* trusty. Sorry if that was not clear in the original comment.

It only affects *xenial*

Directly at login after reboot I had many prompts to send a bug report about kernel oops. I tried to count them. think this report is responding to the 26th prompt to send a bug report, and a few seconds later there was one more prompt to send a bug report.

I think it is a duplicate of the bug report #1551041

Before this reboot and login, I had started to suspect than the Aureal sound card is starting to fail, so I rebooted into

1. The old Precise system with the 3.2.0-97-generic-pae kernel

2. The newer Trusty system with the 3.13.0-79-generic kernel

Both of these systems work well. There is no sign of failure of the Aureal sound card, and there are no kernel oops in precise and trusty.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.5 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I have tried,

$ uname -a
Linux xenial32 4.5.0-040500rc7-generic #201603061830 SMP Sun Mar 6 23:43:15 UTC 2016 i686 i686 i686 GNU/Linux

but it is the same (this kernel does not solve the problem). Instead, I suspect another bug. Please look at

comment #13

-o-

I don't know how to add a tag

[sudodus (nio-wiklund)]

OK, I think I managed to add the tag 'kernel-bug-exists-upstream'
