Subject:  w83627ehf can not be modprobed as of 3.3-rc1

Hi guys,

I don't know the importance of this, or if it is even a bug, but I get
a difference in behavior when updating from 3.2 to 3.3:

# modprobe w83627ehf
FATAL: Error inserting w83627ehf
(/lib/modules/3.3.0-rc1-ARCH/kernel/drivers/hwmon/w83627ehf.ko):
Device or resource busy


from dmesg:

w83627ehf: Found W83627DHG chip at 0x290

it instead of the native driver

Hi,

Normally the kernel command line "acpi_enforce_resources=lax" gets around the problem (BIOS marking the hw chip IO addresses as being owned by the BIOS). I know this was deprecated a few versions ago, so maybe it's been disabled in 3.3

Regards
Ian Dobson
