Hi, using aic79xx under 2.6.12 still (as it has done since the beginning) fails for me; 2.4.23+ is running fine. 2.4.23: scsi1 : Adaptec AIC79XX PCI-X SCSI HBA DRIVER, Rev 1.3.10 <Adaptec 29320 Ultra320 SCSI adapter> aic7901A: Ultra320 Wide Channel A, SCSI Id=7, PCI-X 67-100Mhz, 512 SCBs scsi2 : Adaptec AIC79XX PCI-X SCSI HBA DRIVER, Rev 1.3.10 <Adaptec 29320 Ultra320 SCSI adapter> aic7901A: Ultra320 Wide Channel B, SCSI Id=7, PCI-X 67-100Mhz, 512 SCBs blk: queue f39bfa18, I/O limit 4095Mb (mask 0xffffffff) scsi2:A:5:0: DV failed to configure device.

Termination is okay. Seems like a strange driver problem. What to do?
