Subject: Patch to make ymfpci legacy address 16 bits
Date: Tue, 8 May 2001 20:37:05 -0400 [thread overview]
Message-ID: <20010508203705.A6496@devserv.devel.redhat.com> (raw)
Hi:
I found that every time I run a 2.4 on my laptop, APM locks up
the machine. Apparently, legacy YMF code enabled decoding of
10 bits of I/O address. A call to APM BIOS touched that and
somehow the system locked up.
If Pavel Roskin, Daisuke Nagano or someone else do not mind,
I want this in stock kernel.
