Title:
Fan on full speed without noapic or nolapic on HP 6715s
Status in linux package in Ubuntu:
I made a mistake, 4.4.0-34 does not boot with normal fan speed without
noapic. Instead, it seems the change/break appears between 4.2.3 and
4.2.4. I will try to bisect there. Here is the updated list:
4.1.0: fan ok, 32-bit FADT
4.1.1: fan ok, 32-bit FADT
4.1.2: fan ok, 32-bit FADT
4.1.3: fan ok, 3
I have done some testing of different kernels from the mainline
repository, omitting the noapic parameter to see if they start and how
the fan behaves. This is the result. Kernels using 64-bit FADT cause the
machine to malfunction, as per:

Without adding noapic or nolapic to boot parameters the fan will run on

I can confirm 4.8.0 rc1 works great with noapic/nolapic and
"acpi_force_32bit_fadt_addr". Without the last parameter it uses 64-bit

Interestingly, mainline kernels 4.3.6, 4.2.8 and 4.1.29 seem not to
honor the parameter and use 64-bit adress no matter what.

I did some further testing and it seems I have found a culprit and a
solution. In older kernel versions (3.19.8 and 4.0.9 worked flawlessly
without extra boot parameters) I get something like this when booting:
ACPI BIOS Warning (bug): 32/64X address mismatch in
FADT/Pm2ControlBlock: 0x8800/0x
I did get the system to boot in 4.4.0-34 without noapic and nolapic -
but the fan was running on full (separate issue?). However, the system
seemed even slower than when booting WITH said parameters.
