INIT PANIC

DrDoverylittle · n00b Joined: 15 Oct 2004 Posts: 41

Power cut messed up my gentoo, now when it boots,
the harware is detected ok by the kernel, then the root partition is mounted
then just after free kernel memory is freed up,
i get
INIT PANIC: segmentation violation

i tried going in with the gentoo install disk and mounting all my drives so i could go in
and have a look, but when i try and chroot into my root partition i get a seg fault.

what would you think is broke and what would you do to fix this.

The only thing i can think of is to reinstall gentoo, would only have to do the system
as my /usr /home /boot /opt are on separate partitions, so a quick reinstall of
the system files might work, all my packages would be ok since my /usr partition is untouched.
I could just copy back my world file so it knows what is installed.

This sound sensible, any other ideas ?

Thanks

I'd start by doing a disk check.

Disk check and bad blocks was clean.

Any other ideas to what could cause a seg fault ?

Ah well, time to buy a UPS me thinks.

It's not a pretty picture, but the power out may have buggered your memory...

I'd also consider switching everything over to ext3 or reiser if you don't use them already.

Did a full mem test using latest verion of memtestx86,
no problems found there.
Also i am on ext3 already.

Tried booting up using a Knoppix CD and couldn't get that to work either,
had to turn off apic to get it to do anything,
and the whole thing just freezed after detecting sound card.
Not sure what it tries to detect after sound card, but that might
be the thing thats buggered.

As i said in my first post, i already have,
I tried the 2004.3 loaded fine, but couldn't chroot into system.

So downloaded 2005.0 and tried that,
it loads up fine, had to use noapic option, as with the knoppix,
not sure what that means though.
Still couldn't chroot into system ( i was wondering whether it was
because i had updated to 2.6 kernel, although i was using smp option
on 2004.3 for 2.6 kernel )

Going to just wipe my root partition and start again

Since i am having to use noapic option on the live cd
and my bios says that i have apic set,
does this mean my BIOS is messed up ?

Is this a problem?
don't know enough about it to know if i should worry about this.

No.. it means that your motherboard doesn't deal with it very well.

By no means all motherboards that can support the CPU APIC, actually do.
