Subject: ISA DMA controller hangs
Date: Sat, 28 May 2005 15:38:24 +0200	[thread overview]
Message-ID: <42987450.9000601@drzeus.cx> (raw)

I've been having some problems with ISA DMA transfers failing. They work
fine until the machine does a suspend-to-ram. After that all DMA
transfers stall. Does perhaps the DMA controller need a kick in the ***
after a suspend? I'm no expert on the ISA DMA controller so I could use
some help here.

Rgds
