Subject: advansys adp940 on ppc (2.4.20)
Hi,
I've recently started using an old Advansys card in a powermac clone,
and am experiencing an odd problem.. Accessing stuff on the advansys
scsi bus is very slow - like 30k a second or less. But if I play an mp3 while
accessing the disk, it starts going at least 1mb/sec. The soundcard
uses dma. I was thinking maybe there is some sort of dma
setup/completion problem and the soundcard makes advansys dma start working
right? I don't know. It also seems to help to access data on the other
controller while trying to use the advansys controller, but not as much
as playing sound does.
Any suggestions?
I've included output from various things below, hoping some of it will
be useful.
Thanks,
Kevin
hdparm -t output while playing an mp3:
