Subject: 2.6.26-rc1 regression: ISA DMA broken (bisected)
Date: Fri, 09 May 2008 03:37:54 +0200 [thread overview]
Message-ID: <4823AAF2.7070102@keyaccess.nl> (raw)
Good day.
commit 8779f2fc3b84ebb6c5181fb13d702e9944c16069
"x86: don't try to allocate from DMA zone at first"
breaks all of ISA DMA. Or all of ALSA ISA DMA at least. All
ISA soundcards are silent following that commit -- no error
messages, everything appears fine, just silence.
It won't just revert due to 32/64 merge.
Rene.
