Comment 36 for bug 571258

I'm pretty sure I'm having this issue too. I cannot boot into Ubuntu at all, as the boot crashes both in normal and recovery mode. I tried recovery mode and wrote down everything that appeared on the screen. It was:

udev[349]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/01-mountmanager.rules:6
udev[349]: BUS{}= will be removed in a future udev version, please use SUBSYSTEM{}= to match the event device, or SUBSYSTEMS{}= to match a parent device, in /etc/udev/rules.d/01-mountmanager.rules:6 (these appeared with "...../rules.d/01-mountmanager.rules:8" and "...../rules.d/01-mountmanager.rules:11" as well)

/dev/sda5: clean 318493/4096000 files, 9640602/16358178 blocks

init: plymouth-splash main process (586) terminated with status 1

I can currently only boot my Win7 partition. The Ubuntu one crashes every time, so I'm not sure how I can debug this further...?
