[Bug 1938013] Re: 4.15.0-151 is freezing various Intel machines (i5-3gen, i5-5gen reported)

2021-07-28 Thread Callum Fare 
I'm seeing similar behavior after updating to 4.15.0-151, with multiple
crashes and hangs. My CPU is a i7-6600U.

The message in the dmesg log from the last crash is 'BUG: unable to
handle kernel paging request at 006a18e6bfe5'

I've attached the full trace in case that helps. I also seemingly have
some older (but after updating to 4.15.0-151) crash logs in /var/crash/
that I can also share if these are helpful.

[Bug 1801537] [NEW] Mouse input lag and stuttering audio USB ('irq 18: nobody cared')

2018-11-03 Thread Callum Fare 
Public bug reported:

With both the latest lowlatency kernel on 18.10 (4.18.0-10) and
previously with 4.15 on 18.04 the system is barely usable due to input
lag from the mouse and stuttering audio. This only starts a minute or
two after startup. Despite this graphics performance seems unaffected
and the CPU usage isn't abnormal. Both my mouse and audio device are USB
devices, and the dmesg log shows problems with the irq I think is
associated with the USB controller.

This issue does not exist in any mainline kernel I've tried -
4.16.0-041600-lowlatency, 4.18.0-041800-lowlatency,
4.19.0-041900-lowlatency. This suggests the issue is specific to the
Ubuntu kernel.

I've tried booting with the 'irqpoll' option but this didn't make any
difference.
