Hi, I'm running a 2.4.18-14smp kernel with the 6.2.28 aic7xxx driver. The system hangs when doing I/O to the hardware raid disks attached to the aic7899 interface. When the system hangs there is nothing written to the logs, a running top shows nothing unusual (lots of memory, sway and a reasonable load average). The keyboard does not respond and video is blank. The network card does not respond to a ping. The only thing unusual with this system is that the hardware raid controller is set up to show 8 devices using 1 scsi id and 8 lun. So where to look? Is it a problem with the aic7xxx driver, the interrupt system in the compaq or the phase of the moon. As a sided note: the raid controller using this configuration was moved over from a DL380 G1 machine running RH7.1 (unknown aic7xxx version) where it worked without problems for over a year.
