Hello to the list,
My system is a PIIIDM3 Supermicro mainboard, i840 chipset with integrated
Adaptec AIC-7892 SCSI controller. It has attached two Seagate Barracuda 9Gb
Hard disks.
First of all, the integrated EEPRO-100 didn't work with Linux (intermitent
problems) so I had to install a Realtek 100Mbits card and disable the Intel.
When I put the server in production, about an hour later SCSI bus begins
reseting on an endless loop. I upgraded the aic7xxx.c to the latest version
and had same results. Later I put aic7xxx=no_reset in the boot and enabled
the use of TCQ in the kernel to see the results. I know that "no_reset" only
apply at boot time.
The server is still running after 1,5 hours. Don't know if it will crash
later. Here is the actual aic7xxx initialization (with no_reset and TCQ
enabled):
(scsi0) <Adaptec AIC-7892 Ultra 160/m SCSI host adapter> found at PCI 3/4/0
(scsi0) Wide Channel, SCSI ID=7, 32/255 SCBs
(scsi0) Downloading sequencer code... 392 instructions downloaded
(scsi0) Not resetting SCSI bus. Note: Don't use the no_reset
(scsi0) option unless you have a verifiable need for it.

Any ideas?
