Dmesg with bug

The bug message found in the dmesg log attached to this bug appears with a high probability - but not always - when I release the eject lever to exchange the drive in the ultrabay slot. I'm not sure if this bug is a regression of 2.6.30, because I did not change the drive in the ultrabay for several months. Maybe it was already in 2.6.29 or before. 

The attached dmesg output already contains a patch from Henrique de Moraes Holschuh that can be found here:

Henrique's comment:
Something is causing ACPI devices to have NULL for dev_name().  This broke thinkpad-acpi.
