If that doesn't help perhaps disable CONFIG_HID_GYRATION, but from your other oops something more seems to be broken anyways.This is a static kernel - no module support. Anyway, I also tried without CONFIG_USB_HID (which pulls in all the other HID_* things) but no luck.However, disabling all of HID (CONFIG_HID_SUPPORT=n) makes the system boot (Previously HID, HIDRAW and HID_SUPPORT were still enabled).
It's suspicious if you don't have such devices, that would point to something being confused in the driver probing layer.
However, I still see panics on boot occassionally, tho not so often or reproducible. So far only on dl385 (opteron) systems.
Multiple systems and the same oopses?
And all of the backtraces go through sysfs_new_dirent() near the top.
Please post full oopses. -Andi -- ak@linux.intel.com -- Speaking for myself only.
