I'm having panics or hard freezes when starting X with an Intel
video card. The machine is able to start old X+twm without problems but
when I try gnome3 (in normal or fallback mode, doesn't matter) the
machine panics or hard freezes.
This doesn't happen when running X with vesa. With vesa the gnome is
able to start in fallback (no composition) mode. Also, an old i386 with
an nvidia card is able to run that gnome3 with composition so I'd say it
has to do with the intel card.
These are the specs of the machine:
FreeBSD 10.0-CURRENT #4 r+3dc57aa: Wed Jul 17 15:13:07 CEST 2013
FreeBSD clang version 3.3 (tags/RELEASE_33/final 183502) 20130610
Video Card: Intel chipid=0x00468086
The debugging knobs in the kernel config are there. I can also
confirm that I can break to the debugger with CTRL+ALT+ESC before
starting X. The world was build without debug symbols.
Because the machine runs with an Intel card, I had to use my $work
dockstation to obtain a serial port and do the debug via serial port
with another machine.
When starting X, either the machine freezes hard (and so no
CTRL+ALT+ESC) or the machine panics. It has never executed X without
panics or freezes.
I was able to obtain a core dump, the results are at:
I was unable to dive any further because the dump only shows the
kernel side of things. The bt only seems to show the kernel side and the
user side of things seems to be corrupt.
Any other info I can obtain from the machine in the moment of the
panic, let me know. I can easy do the debug via serial port.
Salut i força,
