The installation of NetBSD 3.0 (i386) itself went fine but after the reboot I got the following error message and was stucked in the db prompt:

[snip]
azalia0: playback: max channels=2
uvm_fault(0xc0825720, 0xc1c09000, 0, 1) -> 0xe
kernel: page fault trap, code=0

A backtrace gave me:

I tried the current kernel (ftp://ftp.netbsd.org/pub/NetBSD-daily/netbsd-3/200601050000Z/i386/binary/kernel/netbsd-GENERIC_LAPTOP.gz).
Same problem.

I tried a modified kernel from Stéphane Witzmann. This is just a current kernel with a printf before each strlcpy in azalia_mixer_init, that will help identify which one fails. It will print "AZALIA DEBUG n" with n between 1 and 16. When I boot this kernel I get the following AZALIA DEBUG messages:

AZALIA DEBUG 9
AZALIA DEBUG 10
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 5
AZALIA DEBUG 6
AZALIA DEBUG 5
AZALIA DEBUG 6
AZALIA DEBUG 5
AZALIA DEBUG 6
AZALIA DEBUG 5
AZALIA DEBUG 6
AZALIA DEBUG 4
AZALIA DEBUG 4
AZALIA DEBUG 4

When I disable the Azalia driver at boot, the boot is successful.
>How-To-Repeat:
Install NetBSD-3.0 on LENOVO Thinkpad Z60M.
>Fix:
None.
