I know this for a fact, since Justin used my 3950U2 to get things working a couple of weeks ago: ahc0: <Adaptec 3950U2 Ultra2 SCSI adapter> rev 0x00 int a irq 12 on pci0.10.0 ahc0: aic7896/97 Wide Channel A, SCSI Id=7, 16/255 SCBs ahc1: <Adaptec 3950U2 Ultra2 SCSI adapter> rev 0x00 int a irq 12 on pci0.10.1 ahc1: aic7896/97 Wide Channel B, SCSI Id=7, 16/255 SCBs He checked support for that card into -stable on March 22nd/23rd, in revision 1.5.2.3 of sys/pci/ahc_pci.c, and revision 1.16.2.4 of sys/dev/aic7xxx/aic7xxx.c. The reason that the 3.1 release notes say that the 3950 is supported is that Justin has a prerelease 3950 board that works just fine. But, as it turns out, they changed the PCI ID and some of the features for the "real" 3950, so the kernel wouldn't recognize it. (for instance, his prerelease board has external SRAM, but my production 3950U2 does not) Anyway, you should be able to get things working if you get one of the post-March 23rd snapshots from here: ftp://releng3.FreeBSD.ORG/pub/FreeBSD/snapshots/i386 The board seems to work fine for me, but I've only got 4 narrow 2gig Seagate Hawks on it, so I'm hardly pushing it. > > After trying 3.1-REL, 3.1-STABLE and 3.0-REL it still won't see the > > second scsi card.
