The backtrace looks related to the "override DSDT via initrd" patches Jeff
updated

This would be a SUSE specific patch and a bug at bugzilla.novell.com should
get opened. Please add me to CC.

Sigh.

Yep. fsnotify isn't initialized yet. I'll disable the patch. I'm not
sure if/when I'll re-enable it.
