Hi, can anyone help me interpret the following lines from dmesg. This is
on a new i7 laptop with SSD drive that should be booting in under 30
seconds but has this 90 second delay involving bbswitch. The ACPI
Warning line here also shows up 20 or so times 1 second earlier, and
then a few times later (at 103 seconds). My reading about bbswitch took
me to confusing, sometimes conflicting, often not current, info on
disabling modules, changing graphics drivers, or other suggestions with
potential to disrupt DayJob for long periods! I'm not at all clear on a
good approach here.
Any pointers on where/how to investigate further are welcomed.
Regards
Roger
