Hi,
I'm running a build of LFS-SVN (latest version). So far everything works
fine, but during bootup I get an error message from udevd and the "Send
this bugreport..." message.
When the udev bootscript is running, I get this message on my terminal:
udevd-event[992]: wait_for_sysfs: waiting for
'/sys/devices/platform/i8042/serio0/serio2/bus' failed
Right after it, the kernel reports:
IBM TrackPoint firmware: 0x0e, buttons: 3/3
input: TPPS/2 IBM TrackPoint as /class/input/input3
(serio0/serio2 is the TrackPoint).
The bugreport file is attached.
Does the attached kernel patch help?
