I recently came across these issues attempting to boot tc-4.1 on a MacBookPro5,5
Issue #1 on boot
"...Starting udev daemon for hotplug support....Done.
apple 0003:05AC:0236.0003: claimed by neither input, hiddev nor hidraw
apple 0003:05AC:0236.0003: hw start failed"
My interpretation of this is likely no kernel support for the apple keyboard/track pad..??
no big deal I guess as long as there is a keyboard..
Issue #2 on boot
"Sending discover...
ata1: exception Emask 0x10 SAct 0x0 SErr 0x1990000 action 0xe frozen
ata1: irq_stat 0x00400000, PHY RDY changed
ata1: SError: { PHYRdyChg 10B8B DisPar LinkSeq TrSTATrns }
failed in waitforX
tc@box:"$ Sending discover...
No Lease, forking to background"
resulting in no boot
My interpretation of this is while the network and video errors look suspicious, I believe possible file system corruption on a HDD or a physical connection with the HDD caused this problem bring the whole system to a halt. Oh and do to the system freeze am unable to recover the dmsg
I have yet to see the outcome of my diagnosis so meanwhile, I'm really interested in what the hardware guru's think about this?
