Bug Description
With Quantal amd64, the machine fails to boot without additional kernel parameters. This is reproducible in 3.5.0-18-generic 3.5.0-18.29 and 3.6.3 mainline. This is not reproducible with Quantal i386.
A Ubuntu release bisect revealed the regression is going from Lucid amd64 to Maverick amd64.
Here's more detailed description of dependency between used kernel flags and boot process:
1. acpi=off - every boot succeeds, but laptop heats very fast (CPU fan also is very loud)
2. acpi=noirq - not every boot succeeds (approximately 2 from 8 are successful. starting from 3.5.0-10~ubuntu kernel and 3.6.0 mainline, on earlier kernels - every boot succeeds)
WORKAROUND: Boot with kernel parameters:
acpi_backlight=
There's an article on Ubuntu Wiki saying that linux on Dell XPS 15z should be booted with acpi=noirq parameter:
