Public bug reported:
I've installed intrepid on my fujitsu-siemens s7110. After installing
linux-image-2.6.27-1 the system does not boot every time. When booting I
get this message in syslog

[ 136.701891] ---[ end trace dc661a0b65e4cc99 ]---
When system is not booting it mostly hangs when initializing udev. The
laptop gets louder so I think the load is increasing. The sysrq does not
work in this state.
