I too have some problems with alsa on my Z60m Thinpad, similar to what
Jaroslaw Gorny.

When i boot my laptop, it sometimes hangs on attempting to load alsa.
It happens randomly, sometimes it starts normal, sound ok, everything perfect.
Sometimes it hangs on loading alsa modules, it just hangs on ::
loading snd-card-0.
by mistake i found out that i can skip this by hitting ctrl+print screen.
Then, i keep getting these messages in my syslog::

Jul 19 13:22:31 newroot ACPI: PCI Interrupt 0000:00:1b.0[A] -> Link
[LNKA] -> GSI 11  (level, low) -> IRQ 11
newroot printk: 11 messages suppressed.
newroot azx_get_response timeout

Some details on my hardware/software:
IBM thinkpad Z60m, 2531w25, Linux newroot 2.6.16-gentoo-r13 #1 PREEMPT
Mon Jul 17 22:50:07 EEST 2006 i686 Intel(R) Pentium(R) M processor
