Comment 16 for bug 89892

I experienced the same problem and I think I solved it by moving /lib/modules/2.6.22-9-generic/kernel/drivers/char/hw_random/intel-rng.ko to some other place where it can't be found at boottime. I've succesfully restarted my laptop five times in a row now without any issue. I'm running Gutsy, but the fix should work with Feisty too.

Can someone else confirm this is workaround works for them?
