>Description:
When I try to load snd_neomagic on my Omnibook 900 I see (in verbose mode)
pcm0: <NeoMagic 256AV> mem 0xfe700000-0xfe7fffff,0xfe00000-0xfe3fffff irq 10 at device 0.1 on pci1
than laptop frozes.
I tried adding hints for pcm0 as was suggested for my laptop before relase 5.X, turned on verbose and got: (there may be typos in my report, since I copied it from screen)

I had this problem with my first intallation (5.4 RELEASE), than, afer last crash corrupted my kernel dir, I installed 6.0 and had the same problem again.
I surfed the mailing lists, found this problem already asked once with a differed laptop, but the only answer was "this must be a bug" and non solution, nor bug report here, so I'm without any clue on how to fix this.
I should add that my laptop is reported as "FreeBSD compliant" since 3.1 and this was my main reason for trying to install freebsd on it.
Also I notice that each time snd_neomagic appears on a dmesg report it is preceded by snd_pcm.ko , while I could only load sound.ko.
>How-To-Repeat:
On FreeBSD 5.4 I tested:
kldload snd_neomagic
set sound and snd_neomagic modules to yes in /boot/defaults/loader.conf
boot a kernel with sound and snd_neomagic
On FreeBSD 6.0 I tried
kldload snd_neomagic
