SubjectRe: 2.6.13-rc6-rt6
From
Date
Ingo,

FYI, I ran this on my laptop (Pentium4 HT) and it locked up shortly
after it started INIT. I rebooted, and now it's up and running
with no problems!?! I'll reboot it a few more times to see if it will
lock up again.

Unfortunately, my laptop doesn't have any serial so I don't have much to
debug with it. I'll set up netconsole, but this is not as reliable
under RT, or was this fixed. I remember before that it could call things
that would schedule and had some hooks to keep interrupts on.

Oh, I also did get the message when it started:

WARNING: kstopmachine/859 changed soft IRQ-flags.

The kernel I used was rt6 with my latest patch to the
raw_local_save_flags.

Config attached.
