--- Comment #21 from Takashi Iwai
Then try to boot without ssb module, at least.
I've tried to do it, see above.
edit /etc/sysconfig/kernel and set NO_KMS_IN_INITRD="yes", run mkinitrd
Interesting results: system hangs _later_ (but with the same probability). And before switching video mode.
When you boot in runlevel 3 and NO_KMS_IN_INITRD, i915 won't be loaded. So you don't have to remove it. i915 module is loaded automatically first when you start X.
I then removed i915.ko and reboot into runlevel 3. modprobe worked, KMS switched mode, but I have not seen the messages from modprobe.
So, no hang happened now? Interesting. Can you start X at this stage? (But anyway test without removing i915 in runlevel 3.) If you get any crash after boot by loading i915 or starting X, then we have a better chance to get logs. As mentioned, you can take kernel messages via netconsole on another machine connected via ethernet.
It`s too long to reboot everytime in debug mode. Can I do "modporobe i915; rmmod i915" several times to collect statistics?
Once when the boot succeeded, basically we don't need for initcall_debug option any more. Now it's a usual debugging. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
