Hi
I put my computer into hibernate last night. This morning I could not
save thunderbird email drafts and I rebooted my system. It stopped
before launching X and offered a root rescue shell.
I am using a solid state drive and it's very possible that it just ended
up with a failed sector. It's my understanding that these drives are
fast but less robust then rotary based ones.
This may be nothing but if you have just backed up your data maybe you
could try to hibernate just in case it is a real issue and is reproducible.
Thanks-Patrick
