Hi, I've experienced a problem in the hardware syncrate detection with both kernels2.2.10-ac12 and 2.2.11 : my CD-writer (Plextor PX-R820T) isn't recognized as a Fast-SCSI device anymore. That's a bit strange since the other negociation rates are still OK (particularly my other CDROM). I didn't found yet what the problem is since it seems that a lot of things have been rewritten in aic7xxx.c . The information I can read in /proc/scsi/aic7xxx/0 confirm what the driver says while booting. Have a look at my syslog. I run Linux on a x86 box with an Adaptec 2940U2W (bios version 2.11). ----- Syslog running either 2.2.10-ac12 or 2.2.11 ------------ Aug 11 00:00:54 lagaffe kernel: (scsi0) <Adaptec AHA-294X Ultra2 SCSI host adapter> found at PCI 9/0 Aug 11 00:00:54 lagaffe kernel: (scsi0) Wide Channel, SCSI ID=7, 32/255 SCBs Aug 11 00:00:54 lagaffe kernel: (scsi0) Downloading sequencer code... 374 instructions downloaded Aug 11 00:00:54 lagaffe kernel: scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.19/3.2.4 Aug 11 00:00:54 lagaffe kernel: <Adaptec AHA-294X Ultra2 SCSI host adapter> Aug 11 00:00:54 lagaffe kernel: scsi : 1 host.
