I'm in the process of updating all my CentOS systems from 4.4 to
4.5. One of the systems is spewing out the following error during
INIT: version 2.85 booting
INIT: PANIC: segmentation violation at 0x420! sleeping for 30 seconds
This happens so early in the boot I have no idea what I can do to
debug this. I suspect it is a hardware problem and not something
caused by the "yum update", but I thought I'd mention it here in case
anyone else has any ideas.
Update: I originally sent this message out yesterday, but my email
client used the wrong account so it didn't get posted to the list.
I've since re-imaged this system (thank you Red Hat for Kickstart),
but I am still curious what could have possibly caused this and any
debugging techniques that can be used in this situation.
On a vaguely related note, I also have pondered the following in the
past; if you observe a system booting, you'll see all the "[OK]" and
"[FAILED]" messages. Is there a log somewhere where you can check
later on which services were started and which passed or failed?
