Having been bitten by bld 859, I waited to upgrade from 826 to 889 to see if it was causing problems. As it apparently wasn't, I updated today, created a boot CD and tried to test it. I allowed it to boot without intervention and with the acpi=off noapic switch, both refused to boot giving the message: hdc:drive not ready for command repeatedly, interspersed with occasional: hdc:lost interrupt. I've reverted to 826, which boots fine. I'd appreciate any thoughts on what's going wrong.
