Title:
Fan on full speed without noapic or nolapic on HP 6715s
Status in linux package in Ubuntu:
Confirmed
Bug description:
Without adding noapic or nolapic to boot parameters the fan will run
on full speed, the system is sluggish (can almost see windows
redrawing on screen). On some kernel versions tested, rebooting also
fails.
The parameter(s) were not required in Trusty. I also tested some
Mainline kernels and discovered 3.19.8 and 4.0.9 works without the
parameters. At least 4.1.29 and onward requires noapic or nolapic for
this machine to work properly but I have yet to investigate the
versions between 4.0.9 and 4.1.29.
