--- Comment #26 from Thomas Renninger 2007-10-12 05:21:51 MST ---
Let's clear some things up first to avoid confusion:
- x86_64 kernel boots with normal boot parameters (without acpi=off)
sound card should work then?
- We have a bug in i386 code that even prevents the machine from booting.
The machine always hangs around the same place, but not exactly the same
place. So this could point to an idle/C-state/nohz issue, but this is just
a guess.
I cannot see whether dmesg from comment #24/#25 is i386 or x86_64, those were
both i386 which did not boot without the paramters or with the default kernel?
In general we try to track down an i386 kernel bug here that prevents the
machine from booting. If you see other issues on the x86_64 kernel or anything
else, pls open a separate bug or things will get confusing.
If the i386 kernel (in acpi mode) did not boot without these parameters:
CPUFREQ=off nohz processor.max_cstate=1
and does now boot with them, could you try to pass each of them, to see what of
these three causes the machine to hang.
