I got this problem after installation of FreeBSD 4.6 on an intel P75
system. Any help to get the cdrom working will be appreciated.
Error message is something like:
acd0: READ_BIG command timeout - resetting
ata1: resetting devices .. done
and is repeated several times
I've tried fixes for a similar problem as suggested in later release
notes:
set hw.ata.ata_dma="1"
set hw.ata.atapi_dma="1"
at start of boot and in /boot/loader.conf but this doesn't make
any difference that I can see.
NetBSD 1.5.2 installed straight off and cdrom seems to be fully
functional afterwards (so I should be able to mount a FreeBSD
partition and copy the cd set over from NetBSD).
Below is some hopefully relevant info from both FreeBSD and NetBSD:
