kernel config options

I am not sure what changed bewtween 2.6.29 and 2.6.30, but using the exact same .config file to compile I get a kernel panic.

PANIC: early exception 0e rip 10:ffffffff810a029b error 0 cr2 21810

This is the first time I have reported a kernel problem, so I am not sure what more information I need to provide.  Please let me know and I will be happy to add more information.  

If I need to configure some debug options that will give more output when I boot, let me know what those are as well. If I understand correctly it appears to be a page fault error?

Not sure if it would be useful, but below are some details about my installed libs.

> PANIC: early exception 0e rip 10:ffffffff810a029b error 0 cr2 21810

Is that the only info it gave you?  No stack backtrace?

Comment 2 biohazrd 2009-05-14 23:18:41 UTC

Ok, now this is really strange.  I rebooted to check for additional output, which I don't recall; but it booted fine this time.  I am tending to lean toward a memory problem as the only thing I did different was swap the DIMM's to another slot and turn on ECC scrubbing and patrol.

Odd it failed like 5 times and the other kernel would boot up fine, but after switching memory around it booted up without a problem.

You can probably close this bug.  Thank you for the quick response.

Even more so... Andrew thank you for you involvement with Linux in general!

Comment 3 Phillip Merensky 2009-08-21 14:18:04 UTC

Hello.
I got the same error on one of our servers (PANIC: early exception 0e rip 10:ffffffff810a029b error 0 cr2 21810) and also did not get a stacktrace. Even after recompiling the kernel and rebooting it does not work. However I did not try to reboot after it hung the first time. Tested kernel was 2.6.30-r5. 

emerge --info is:

If you need additional info me know. 

Testing new patches is not that easy because the server is a headless machine without remote management card and restricted physical access.

Thanks in advance
Phillip
