[solved] segfaults, filesystem errors and kernel panics :/

Hi people,

I've been running Arch for a while now with absolutely no problem on an IBM T30 ThinkPad. I was using Firefox/pidgin from wmii, when I tried to access a script called opentape through firefox, which was running on httpd locally. httpd instantly crashed, along with x. I restarted x and checked the messages.log - there were multiple segfaults for httpd, firefox and gconf. I couldn't start firefox, so I attempted a reboot. fsck detected errors in my root filesystem, which I went through and fixed, and rebooted again. It then found errors in my home partition, got to about 30% of the check, then spat out debug information and kernel panicked:

Code:  Bad EIP Value.
EIP: [<00000000>] 0x0 SS:ESP 0068:c03cfe14
Kernel panic - not syncing: Fatal exception in interrupt

Since then, I can't boot using either the vanilla Arch kernel of the fallback image; it just hits the fsck check and kernel panics.

Prior to all this, the only thing I upgraded (if I remember correctly) was qt and one other package that I can't remember through pacman -Syu.

Is this a hard drive failure or something else? I have absolutely no clue about kernel panics or segfaults...

EDIT: Turned out to be a faulty RAM stick. Sorry!

Re: [solved] segfaults, filesystem errors and kernel panics :/

Kernel panic might be related to hardware problem. I doubt it is related to software (operating system + application). If there is too much dust in notebook, PCB connection between CPU and memory might not deliver the voltage correctly, which causes that CPU reads suddenly an invalid code or an invalid address. This is directly mapped to kernel panic.

If you observe this problem just on one hardware, then I suggest you to install another operating system on this hardware. Windows or Linux. If you experience similar problems, then clean the dust in your notebook first. Or localize the problem in your hardware. It might be harddisk problem or memory problem.

Good luck!
