I'm trying to install RedHat 6.1 on my Dell XPS-T450 computer. This machine
has an older Adaptec AHA-2940 PCI SCSI host adapter in it. Everything works
fine until the aic7xxx module loads. At that point, the following messages
are displayed and the system hangs. Been through all of the various setting
in the CMOS and so forth but I don't see any problems. Here are the
SCSI adapter BIOS version message at boot time:
Adaptec AHA-2940 BIOS v1.11S
Everything looks normal up to here...
Loading aic7xxx module
(scsi0) <Adaptec AHA-294X SCSI host adapter> found at PCI 15/0
(scsi0) Narrow Channel, SCSI ID=7, 16/255 SCBs
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.20/3.2.4
<Adaptec AHA-294X SCSI host adapter>
scsi : 1 host.
(scsi0) BRKADRINT error(0x48)
Sequencer Ram Parity Error
PCI Error detected
Kernel panic: aic7xxx: unrecoverable BRKADRINT.
In interrupt handler - not syncing
At this point, the system is hung. I've also seen the BRKADRINT error(0x8).
I think that is just the sequencer RAM parity error and no the PCI error.
This host adapter functions correctly under Windows 98SE so I don't think
that I believe that there is a hardware problem with the card or the basic
setup of the system.
Here's some vital statistics on the machine and OS:
RedHat 6.1 boxed CD (kernel 2.2.12-20)
Dell Dimension XPS-T450, BIOS version A04 (PhoenixBIOS 4.0 release 6.0).
Intel Pentium III 450 MHz.
128 MB SDRAM.
Diamond Viper 770D 16MB.
12 GB IDE disk, 40 CD-ROM, HP CDWriter 8100.
D-Link DFE-530TX PCI Ethernet controller.
Yamaha DS-XG PCI sound card.
ISA serial port board - 2 16550A UARTs, no parallel port.
3Com/USR PCI winmodem (I'm not expecting to use this under Linux but I
do use it under Windows for now so I haven't pulled the card).
The additional serial ports are at 0x2F8/irq3 and 0x2E8/irq5.
I've been digging around on the net but I haven't been able to find anything
very helpful. Any help or advise would be greatly apperciated.
Thanks in advance and best regards to all,
