Hello all. I'm having a strange error message regarding the use of a
Promise ATA66 controller and a 20GB IBM UDMA66 Hard Drive. I've included my
dmesg with this email. Anyways, this Hard Drive works perfectly as far as I
know, but during startup, I get this...
ad4: READ command timeout tag=0 serv=0 - resetting
ata2: resetting devices .. done
ad4: READ command timeout tag=0 serv=0 - resetting
ad4: trying fallback to PIO mode
ata2: resetting devices .. done
Anyone have any idea what this is message means, or a solution to it?
Thanks.
Eric
