Comment 27 for bug 550559

For me its even worse so that Crucial RealSSD C300 only sometimes is recognised even in GRUB stage. When I am lucky and it is found I rarely can bootup until the end ... mostly it stucks at those .... Exception Emask ... frozen .... messages.

Thing got worse with upgrade from Lucid (where bootup and working with the system worked most of the time but those messages above where omnipresent in syslog and i hoped to solve this with dist-upgrade .... failed) - it was hard work to do the upgrade, I had to do it with minimal system without GUI to not get stuck at some installation steps. And now I can not use the system anymore.

Notice that Windows 7 works without a problem, though I notice some kind of delay at bootup before the first bootup screen appears.

The system is Asus P7P55D-E LX and C300 connected to 6 gb/s Marvel controller.
