Nix:
Thanks for the work you've already done with the bisection. Let's see
if we can get to the bottom of this. Would you capture two couple sets
of logs, one without the issue and another set with the commit at issue
included for comparison.
For each set please capture:
a 'dmesg' log with the kernel boot parameters 'debug' and
'ignore_loglevel' added (the entire log from booting),
a capture of 'lspci -t',
and a capture of 'lspci -vvv'.
I'll open a BZ for this issue tomorrow which we can use to attach the
logs while tracking this down.
Thanks,
Myron
