Subject: [gentoo-user] Anyone's kernel getting panicky????

Hi all,
	Just did an eix-sync followed by an emerge -NuD world and then the
manual kernel, nvidia drivers build and grub2 fixup. When I rebooted I
got a kernel panic. It appears to be very early on in the process as I
get minimal stuff flashing up the screen before the panic. Any thoughts
on how to find out what's going wrong?

	The kernel in question is 4.1.2 and I've now rebooted back into 4.0.5
and things are fine. I've looked at dmesg for this boot, 4.0.5, and it
doesn't mention anything about memory being on the way out. My thoughts
are to try and boot again from 4.1.2 and let it panic. Then reboot using
a sysrescude cd and see if dmesg has written anything. Whilst I've got
the sysrescue cd happening, I'll also run a memory check.

	I've done the above, there is nothing in /var/log/dmesg for the
panicked boot, it still contains the data from the previous 4.0.5 boot.
The running of memtest, I let it run for about 3hrs, showed no errors as
well. I'm about to give boot_delay a try to see if I can spot what's
causing the problem and am currently in the process of fixing this up:

Would anyone have any other thoughts?

	Thanks in advance,
