Hi,
I have a system that won't do large compiles like the kernel.
The parts list includes:
Gigabyte GA-6BXDS rev 1.7 MotherBoard
AIC-7895P on the mobo
CH A - bus 0 targ 0 lun 0 - Seagate Barracuda ST34501W
CH B - bus 0 targ 1 lun 0 - Seagate Barracuda ST39173LW
bus 0 targ 2 lun 0 - Seagate Barracuda ST39173W
256MB ECC RAM (2*128MB sticks)
1 - 400Mhz PII 512K L2
Trident 9875 VGA
Intel EtherExpress Pro 10/100+
3.5" Floppy 1.44MB
104-key Keyboard
When compiling the kernel with all parts installed, it will get partway
through the compile and hard lock. The keyboard will not respond and a
power-cycle is required.
If I remove the EtherExpress card the compile completes. So I bought
a new card thinking that this one had gone bad. No such luck. I have
swapped out the memory. I've swapped the video. I can't swap out the
disks but have removed all but the 4.5GB drive with the same results.
The only wierd thing in my dmesg output seems to be a warning about using
too many ports on the controller even when only one port is in use.
So, I turn to you guys. What have I missed? Is there a problem with the
"P" model of this SCSI chip? My other machines are using the AIC-7895
without problems. The SCSI BIOS is set to auto-Termination and the last
drive on each of the two cables is terminated.
dmesg with GENERIC kernel: (I've stripped the unfound driver messages)
