Kernel 9.1 panic with azalia

[tlaronde%polynum.com@localhost]

Hello,

I was trying to update a server, running a NetBSD 7.1.1 (amd64) to
NetBSD 9.1.

The new kernel panics at boot time with azalia (it is not crucial since
it is a server and I have no use with it but I have added the support
since it's here and 7.1.1 has no problem with it).

It's a production server so I can not easily do tests. Here is the
message (reconstructed by hand from written info---may contain
blunders):

azalia0: codec[2]: 0x1106/0x0441 (rev. 1.0), HDA rev. 1.0

Note: with the 7.1.1 kernel, for azalia I have:

azalia0: codec[2]: 0x1106/0x0441 (rev. 1.0), HDA rev. 1.0
azalia0: codec[3]: 0x8086/0x2806 (rev. 0.0), HDA rev. 1.0

The size in the panic is non sense.

Hoping this can give enough clue to debug.

TIA,
