Title:
100% cpu usage with 4.8 kernel after upgrade to 16.10
Status in linux package in Ubuntu:
Incomplete
Bug description:
After upgrading my Sony Vaio Pro 13 to Lubuntu 16.10 and logging in
for the first time, I noticed the fans were spinning crazy fast. Since
nothing was open and I hadn't done anything since the upgrade yet, I
looked at top. There it showed systemd-journal and rsyslog using 100%
CPU.
I looked at /var/log/syslog and there was a flood of messaging
continually being appended of the form:
ACPI Error: no handler or method for gpe ... disabling event ...
The system was still somewhat usable, so I tried checking for updates,
but there wasn't anything to update. Since I never encountered this
error before, I tried installing a mainline kernel (4.9) from the
Ubuntu mainline kernel PPA. I booted into the new, mainline kernel and
no more 100% CPU usage. The only problem with using this kernel is
that I can't use VirtualBox anymore because dkms has a compilation
issue when building against the 4.9 kernel.
Before upgrading to 16.10, I was using Lubuntu 16.04 with whatever the
latest 4.4 kernel was at the time that 16.10 was released, which also
worked just fine.
The current (as of this writing) 4.8 kernel that is still causing
problems is 4.8.0-32.
