Hi Alan,
Thanks for your email, I did some testing please see the attachments.
Loading the eeepc-laptop modules takes 17 seconds! So I am sure this is
causing the delay :D
time modprobe eeepc-laptop
real 0m17.319s
user 0m0.008s
sys 0m0.060s
The printk.time=1 did not do anything on my system, also see the logs,
and according /proc/modules I am also not using the pciehp module.
Best regards,
Jelle de Jong
# this does not work
