>Description:
When trying to boot NetBSD 6.0_BETA on a system which contains a
ESS Solo-1 PCI AudioDrive ES1946 Revision E soundcard the following
kernel panic occurs during boot:
...
eso has not been converted to device_t
eso0 at pci0 dev 10 function 0: ESS Solo-1 PCI AudioDrive ES1946 Revision E
panic: kernel diagnostic assertion "mutex_owned(&sc->sc_intr_lock)" failed: file "/usr/src/sys/dev/pci/eso.c", line 673
fatal breakpoint trap in supervisor mode
...

This kernel panic does not occur with NetBSD 5.1:
...
eso0 at pci0 dev 10 function 0: ESS Solo-1 PCI AudioDrive ES1946 Revision E
eso0: interrupting at irq 5
audio0 at eso0: full duplex, playback, capture, mmap, independent
opl0 at eso0: model OPL3
midi0 at opl0: ESO Yamaha OPL3 (CPU-intensive output)
mpu0 at eso0
midi1 at mpu0: ESO MPU-401 MIDI UART (CPU-intensive output)
joy0 at eso0
joy0: joystick not connected
...

>How-To-Repeat:
Try to boot NetBSD 6.0_BETA on a system which contains a soundcard
handled by eso(4).

 this seems obvious.  eso_reset() is called without sc_intr_lock held
 from eso_attach().  eso_attach() is the only caller, so it's probably
 safe to simply remove the KASSERT() from eso_reset().

 that it currently asserts.
