ESS Technology Maestro-2E on CURRENT

[Oleg R. Muhutdinov]

Hi

I have Compaq ARMADA M700 with sound ESS Technology Maestro-2E:

boot -v

setmap (66c000, 4000), nseg=1, error=0
pcm0: pch[3].offset = 0x24000

When I boot my box, sound is works fine, but
when I apm -Z (apm -z not work) sound are
broken.

On FreeBSD 5.0-RELEASE in this situation
sound works fine, and apm -z (zzz) works fine.

Any ideas?
Thanks

P.S. Sory, my English is not good, but I all understand :-)
