Maestro-2E no workee in 5.2.1-RC2

[Joseph Dunn]

Hello,

I recently upgraded from FreeBSD 5.1 to 5.2.1-RC2 because I needed
support for my Atheros-based wifi card. However, my Maestro-2E sound
card does not function under 5.2.1, whereas it worked fine with 5.1. For
what it's worth, the machine is a Toshiba Portege 7020CT, and ACPI is
(necessarily) disabled. Here is the kernel output that occurs when I
run "kldload snd_maestro":

Any help/suggestions would be greatly appreciated.
