Hi Justin and everybody else in this list, I have a TYAN S2665 Thunder i75505 mainboard with aic7902 controller. I tested several new kernels: linux-2.4.21 linux-2.4.21-ac4 linux-2.4.22p2 linux-2.4.22p3 linux-2.4.22p5 I think that at least the last to kernel includes the most current aic79xx driver (1.3.10). The controller should have transfer rates of 320 MBytes/sec on both busses. In the adaptec bios the controller is configured, to have these rates. But when I am booting linux, I get the following: SCSI subsystem driver Revision: 1.00 scsi0 : Adaptec AIC79XX PCI-X SCSI HBA DRIVER, Rev 1.3.10 <Adaptec AIC7902 Ultra320 SCSI adapter> aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI-X 67-100Mhz, 512 SCBs scsi1 : Adaptec AIC79XX PCI-X SCSI HBA DRIVER, Rev 1.3.10 <Adaptec AIC7902 Ultra320 SCSI adapter> aic7902: Ultra320 Wide Channel B, SCSI Id=7, PCI-X 67-100Mhz, 512 SCBs blk: queue f793ee98, I/O limit 4095Mb (mask 0xffffffff) (scsi1:A:1): 40.000MB/s transfers (20.000MHz, 16bit) (scsi1:A:2): 40.000MB/s transfers (20.000MHz, 16bit) (scsi0:A:3): 320.000MB/s transfers (160.000MHz DT|IU|QAS, 16bit) (scsi0:A:4): 320.000MB/s transfers (160.000MHz DT|IU|QAS, 16bit) I can work with both busses, but the bus1 is also with bonnie++ at least 50 % slower than bus0: ---Sequential-Output----------- --Sequential Input-- Size Per Char- --Block-- -Rewrite- Per Char- --Block-- Machine GB K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP bornholm 7 28034 97 50599 24 28010 9 30579 88 58413 11 /dev/scsi/host0/bus0/target3/lun0/part2 bornholm 7 27257 94 53227 25 29197 10 31238 90 56044 9 /dev/scsi/host0/bus0/target4/lun0/part2 bornholm 7 19730 69 36062 17 17463 5 29496 84 35135 5 /dev/scsi/host1/bus0/target1/lun0/part2 bornholm 7 19775 68 36764 17 17339 5 30150 86 35168 5 /dev/scsi/host1/bus0/target2/lun0/part2 Do you mean that the driver is responsible, or is it a hardware problem? I would appreciate very much any hint. With best regards Juergen
