Re: NetBSD 8.0-BETA hangs at boot at xHCI (so does netbsd-7)

Hi and sorry for top posting, I'm using the web client.

I actually didn't know I could do that, so thanks for the suggestion. I
will not have access to my machine for a few days, so I haven't tested, but
I will post the results when I do have a chance to try.

NetBSD 8.0-BETA hangs at boot at xHCI (so does netbsd-7)

Hi!

I currently run netbsd-7-1 amd64 on a m4a88td-m evo board with an Amd
Phenom processor, which boots fine.

I decided to try the netbsd-7 branch, which didn't boot, then I decided to
try the netbsd-8 branch, since I'd like to run that when it comes out.

Both the netbsd-7 and the netbsd-8 branches behave in the same way.

They hang at:

uhub0 at usb0: vendor 1033 (0x1033) xHCI Root Hub (), class 9/0, rev
1.00/1.00, addr 0
uhub1 at usb1: vendor 1033 (0x1033) xHCI Root Hub (), class 9/0, rev
2.00/1.00, addr 0

I can't break to the debugger, since my keyboard and mouse is USB. I tried
compiling a debug kernel, but it doesn't give any further information.

An observation that might not say a thing, it continued when I pressed the
powerbutton, listing OHCI and EHCI, then syncing discs and then crashing to
the debugger with (this from netbsd-8):

fatal protection fault in supervisor mode
trap type 4 code 0 rip 0x804659b0 cs 0x8 rflags 0x10282 cr2 0
ilevel 0 rsp 0xfe810e92acb0
curlwp 0xfe822deed4a0 pid 0.15 lowest kstack 0xfe810e9272c0
kernel: protection fault trap, code=0
stopped in pid 0.15 (system) at netbsd:usbd_fill_deviceinfo+0x220: movsbl1
0(%rsi),%edx

All information is transcribed by hand.

Anything else I can provide that would be helpful?
