Hi I'm having problems with an Adaptec AIC-7890/1 Ultra2 SCSI adapter. under kernel 2.4.0-test10. Under boot, the the two Quantum scsi disks are not detected correctly, and the root partition could not be mounted (because it could not find the disks). Written of the screen: Host: scsi0 channel: 00 Id: 01 Lun:00 Vendor: ÉP Model: @L rev: P Type: Unknown ANSI SCSI revision: 00 Host: scsi0 channel: 00 Id: 02 Lun:00 Vendor: ÉP Model: @L rev: P Type: Unknown ANSI SCSI revision: 00 Going into the scsi bios, and setting the scsi transfer to narrow (40Mb instead of 80Mb) corrects the problem. Is there any solution to this problem, or won't I ever get my discs up and running 80Mb/sec? Btw. They both gets detected correctly in 2.2.16 in wide mode. The mobo is a P2B-DS, with two PIII-550 Mhz CPU's > cat \proc\scsi\scsi Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: QUANTUM Model: ATLAS 10K 9WLS Rev: UCP0 Type: Direct-Access ANSI SCSI revision: 03 Host: scsi0 Channel: 00 Id: 01 Lun: 00 Vendor: QUANTUM Model: ATLAS 10K 9WLS Rev: UCP0 Type: Direct-Access ANSI SCSI revision: 03 >cat /proc/scsi/aic7xxx/0 Adaptec AIC7xxx driver version: 5.2.1/5.2.0 Compile Options: TCQ Enabled By Default : Enabled AIC7XXX_PROC_STATS : Enabled Adapter Configuration: SCSI Adapter: Adaptec AIC-7890/1 Ultra2 SCSI host adapter Ultra-2 LVD/SE Wide Controller at PCI 0/6/0 PCI MMAPed I/O Base: 0xcc000000 Adapter SEEPROM Config: SEEPROM found and used.
