Re: hdsp + acpi/apm = bug/feature?

["Dan Nyborg" <nyborg@www.vertice.ca>]

hello,

i don't have the up to date patch for acpi and had the same problem even
without the low latency patch. i'm going to hold out upgrading until 2.6...
right now, i'm having too much fun with the hdsp ;) - for two months it sat
idle... dust (yes dust!) collected on it!

big thanks for all your software,

dan.
