photo of the crash/trace
I've been trying to get a Dell Venue 8 Pro (valley view tablet) to boot Fedora
on and off for the last while. Back around 3.12 / early 3.13 it would reliably
boot and even start X with 'nomodeset', but almost none of the integrated
hardware shows up. With recent 3.13 kernels it seems like it almost always
fails to boot, but just occasionally does boot (and like earlier kernels, no X
with modesetting, no wifi, no bluetooth, no sound etc etc).
When it fails, I wind up with what's visible in the attachment: a "BUG: unable
to handle kernel paging request" and a reference to __add_pin_to_irq_node, then
a trace that looks like ACPI / PCI / IRQ stuff. The trace has taint flag W, but
I didn't see any other traces scrolling by earlier in boot. Unfortunately,
can't page up once it hangs - it's just stuck like this.
The kernel I'm using is Fedora's current Rawhide build - 3.13.0-0.rc5.git0.1 ,
which is basically 3.13rc5 - with two patches added that seemed possibly useful
to vlv. one is this:
https://github.com/rjwysocki/linux-pm/commit/b2a51a6d0f96308251cfa41b793c43d0316e3b16
and the other hacks the SDIO ID for the tablet's wifi adapter into the ath6kl
driver:

I doubt either is relevant here.
