Checking one more point .. do the USB ports come up ok if you originally
boot with nothing plugged in? If so (or if not), does that local APIC
error message appear the same then too?
cheers, Ian
PS OT: finally found a USB keyboard but I'd forgotten that my friend's
machine is an SL500, not T500. Moreover, because its keyboard+trackpad
etc is non-working (internally disconnected), I have no way to resume it
without the kbd (and the 9.1-R memstick) plugged in. Even with kbd and
memstick left in and using acpiconf -s3 it suspends ok but is hung after
resume by dabbing power button; no screen and kbd is dead too - sorry,
no help there. OTOH my son just bought a refurb T430 ('doze 7, beats 8
anyway) which I should get to play with a bit this week.
