Description valère monseur 2012-04-09 10:04:41 UTC

I've upgraded from 3.2.9 to 3.3.1 and I face a kernel panic after the messages: "Decompressing Linux...Parsing ELF...done." and "Booting the kernel".

The error message is "PANIC : early exception 06 rip 10 : ffffffff81456a10 error 0 cr 2 0"

I'm running a laptop DELL XPS L501X.
In attach, you can find the output of lspci and lsusb.

I'm running archlinux. You can find the way the kernel is built here:

What other info should I put or action should I take to find where the problem could be ?

Ok, sorry for this report done too early. Seems it's already known in the distro and followed-up:

Mmmm, finally the bug mentionned above is not the problem (at least the workaroung mentionned don't work) -> reopening.

So, my original question remains: what other info should I put or action should I take to find where the problem could be ?

I'm seeing this too. Same hardware, running on Fedora 16 and Fedora 17 Alpha/Beta. Worked for me up to 3.2.10; the update to 3.3 then hit this bug.

It is something to do with the wifi driver: disabling wifi in the BIOS allows the machine to boot (but a laptop without wifi isn't much use).

Simply turning the wifi off with the soft key combo before the GRUB screen doesn't help. I'd hoped that I could get round it by turning it off with the key combo, and then turning it back on after booting, but the panic still happens. And if I turn it off in the BIOS, I can't then turn it back on with the key combo after booting.

Same problem on Dell XPS15/L501X. Had to disable BOTH the wifi and ethernet nic in bios. Disabling just wifi didn't work.

Exactly the same problem here, on the exact same hardware.

Component: 	IA-64
Assigned To: 	platform_ia-64@kernel-bugs.osdl.org

Why is this assigned to IA-64? The Dell XPS is an AMD 64-bit capable intel (i7 - i5 - i3) architecture.
So it should be  x86-64 or i386 (IA 64 is itanium, i7 is not itanium).

I observed the bug with 64 bit kernel, did anyone use a 32 bit kernel?
Comment 9 valère monseur 2012-04-11 14:55:18 UTC
@nathansamson@gmail.com: Indeed it's not Itanium but x86_64. Unfortunately I don't have authority to change the assignee.
Comment 10 j.heather 2012-04-12 21:07:54 UTC
@valere: Dare I suggest opening a new bug with the right architecture? The current assignee has not yet seen fit to comment or to reassign, and this won't get looked at otherwise.

If you do open a new bug, please post the link here so that we can copy our comments across and join in the game.
