Hello,
We have an early boot crash in 3.6 and 3.6.1 on many machines, using
nvidia chipsets. Boot fails in 1 case to 10 boots or 9 cases in 10 boots,
depending on machine.

The head of log, got via serial console(full log attached):

Disabling on-board IDE controller in BIOS seems to workarownd the problem.

Funny URL stuff going on, that is the text for you.

I can not disable IDE, it's in use

You may downgrade the kernel for the time being or try LTS kernel.

thesame · 2012-10-18 13:22:57

Yep, running LTS at the moment.

glenn69 · 2012-10-18 14:25:57

I have the same problem.

You may downgrade the kernel for the time being or try LTS kernel.

How do I accomplish this when I cannot get past boot into the OS?

Also, headkase, which log file are you displaying in your post? I can access my disk via a live cd, but cannot find the appropriate log for my machine.

Thanks

I fixed the link (dropped the l in html).

Boot a live cd and chroot (see the wiki on chrooting).

That's the content of the email that I failed to link to properly.

I guess that if I downgrade kernel, I should also downgrade some other packages? Which ones?

pacman will let you know

Does anyone know if there is a bug number for this? I'm experiencing this bug on my MacbookPro 7,1 (2010) too (I am forced to use IDE as sata is not supported on this machine in bios compatibility mode afaik).

The title of this thread is rather non descriptive. How about name it something like:

kernel 3.6 panic ("kernel NULL pointer dereference in pacpi_set_dmamode")
