Bug#138800: Install hangs w. Supermicro 5011H w. AIC-7899 Ultra 160/m onboard SCSI controller
Package: boot-floppy
Version: 2.2r3, 3 (both)
The system locks up during the kernel load. The bootup is apparently
choking on the aic7xxx driver and locks after downloading sequencer code
from both channels of the SCSI controller. Only cycling power will recover.
I note that a Red Hat (6.1) boot disk which I have on hand successfully
loads the aic7xxx driver as a module, and the hard drives can be accessed,
so this is apparently related to modules or other code included with the
Debian install, and probably isn't due to faulty hardware.
The server is a new Supermicro 5011H with an Intel PIII, 1G, using Intel's
815E chipset. It has an Adaptec AIC-7899 Ultra 160/m onboard SCSI
controller with a SCA backplane between the onboard SCSI and the drives.
The lockup occurs with both the potato install CD and with the compact
rescue disk from testing.
I have recompiled the 2.2.20 kernel without aic7xxx support, and the kernel
loads properly (sans access to the hard drives). If I then try to load
aic7xxx support as a module I again get a system lockup requiring a
power-cycle to recover.
