Summary: applesmc - Sudden motion sensor not recognized on newer
versions of MacBook Pro
Product: Drivers
Version: 2.5
KernelVersion: 2.6.25.9
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Hardware Monitoring
AssignedTo: khali at linux-fr.org
ReportedBy: h_psaier at gmx.at
CC: nicolas at boichat.ch
Latest working kernel version:2.6.25.9
Earliest failing kernel version:2.6.23.*
Distribution: Gentoo / homebrowen kernel
Hardware Environment: MacBook Pro 4.1 of Feb. 2008
Software Environment: Gentoo Stage 3 environment
Problem Description:
On boot all MBP features (backlight control, temperature sensors, ...) are
recogized correctly EXCEPT the sudden motion sensor. However as another user
descibes:
This only occurs if I hard boot to linux. If I first boot to osx, and
then soft boot (restart) to linux, the motion sensor works as
expected.
Now, I don't know how the kernel developer of the module came up with the init
magic, but I am of course ready to supply any debugging/system information
available.
Steps to reproduce:
mainstream kernel 2.6.25.9 on loading the applesmc driver:
applesmc: Apple MacBook Pro detected:
applesmc: - Model with accelerometer applesmc: -
Model with light sensors and backlight applesmc: -
Model with 12 temperature sensors
applesmc: wait status failed: c != 8
applesmc: wait status failed: c != 8
applesmc: wait status failed: c != 8
... (endless same lines)
mactel patched kernel 2.6.25.9 on loading the applesmc driver:
applesmc: Cannot set motion sensor. might not receive some interrupts.
