Description Nathan Samson 2012-04-10 13:26:18 UTC
User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:13.0) Gecko/20120409 Firefox/13.0a2

Booting the kernel 3.3.0 and 3.3.1 fails with an early kernel panic on dell XPS L501X machines.
(PANIC: early exception 06 rip 10:ffffffff81d369ef error 0 cr2 0) directly after Loading initramfs

I've found two forum posts of people with the same problem and exactly the same hardware.

The forum post adds a workaround, disabling the wifi in the BIOS. I did not try this, but it isn't a solution for me.

Reproducible: Always

Steps to Reproduce:
1. Buy a dell XPS Studio 15
2. Install fedora 
3. Upgrade to latest kernel (3.3.1)
4. Reboot and try to boot kernel 3.3.1
Actual Results:  
Kernel panic

Expected Results:  
Boots

I'm seeing this too. Same hardware, same problem. Disabling wifi in the BIOS avoids the kernel panic, but leaves me with a largely pointless laptop.

It's now been reported upstream:

https://bugzilla.kernel.org/show_bug.cgi?id=43076

I'd encourage anyone hitting this bug to add a comment to the upstream entry. The more chatter, the more likely it is to get looked at.

This is a major issue because you can't even solve it by switching distro.

Comment 2 lopezmen 2012-04-17 20:18:44 UTC
I have the same issue running fedora 16 on kernels 3.2.10-3.3.1 but on a dell
studio xps 13 (studio xps 1340).

I could not disable the wifi thru the bios so i couldn't say if is the wifi
or not.

Comment 3 Daniele ViganĂ² 2012-04-18 09:16:28 UTC
Same hardware and same troubles as Nathan Samson

Comment 4 bertu.torrent 2012-04-18 15:35:00 UTC
Same problem with dell studio xps 1340

Comment 5 Daniele ViganĂ² 2012-04-20 16:14:16 UTC
I've recompiled the Fedora 16 3.3.2 kernel from update-testing (3.3.2-1.fc16) with the patch from Tejun Heo (https://bugzilla.kernel.org/show_bug.cgi?id=43098) and I can confirm that now my Dell XPS 15 is booting and working without any issue.

If someone wants to test the patched 3.3.2-1.fc16 I can provide x86_64 RPMs.

Thanks to all.

Comment 14 Johan Godfried 2012-04-24 20:35:36 UTC
I have a Dell XPS17 and I have been having this problem since the first kernel 3.3 update on FC16 x86_64 (The last working kernel was kernel-3.2.10-3.fc16).

I can confirm that kernel-3.3.2-6.fc16 is booting successfully without the PANIC.

Comment 15 Marc Ashford 2012-04-25 23:20:15 UTC
I just ran my updates and I have a Kernel Panic error also. Error: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0). I do not have a Dell. I have a Gateway DX 4200 with Nvidia 9600, Specs found here: http://support.gateway.com/s/PC/DX4200/1015576R/1015576Rsp3.shtml.

I have tried to rebuild the boot partition and it still will not load. I am not able to boot to previouse 3.3.1-3 as the system will not let me install the proper nvidia drivers for that Kernel. The fs is listed correctly as is the 0,0.

I hope an update is pushed before having to move to 17 as I am looking at reinstalling to fix this. Any help would be greatly appriciated!

Thanks,
Marc
