Comment 5 for bug 581847

Exactly the same problem here, running linux-image-2.6.32-24-generid on amd64 host. Each I unplug the powercord, the HDD light blink and the system is completly frozen, reboot is needed. I also notice that if I power on the system witouth the network card plug, I must reboot the system to see the interface. I use Ubuntu for more than 5 years in my daily job, but this is the first time that I have so much critical problems.
