Unfortunately; on my two particular problems, things actually got worse. My "write to the SCSI tape" (recall, this is a wangtek 5150ES - and when I get to the end of the write and the tape is rewinding, I run into trouble) - actually locked up the entire SCSI bus. 2.1.7 only locked up the one process. My only recourse was to reboot. The machine would answer PINGs, but you couldn't telnet or rlogin because there was no disk access. I imagine the first swap would have panic'd. Here's the messages from the console window (which I happened to have up at the time): sd0(ahc0:0:0): SCB 0x0 - timed out in command phase, SCSISIGI == 0x84 SEQADDR == 0x42 st0(ahc0:2:0): abort message in message buffer sd0(ahc0:0:0): SCB 0x1 timedout while recovery in progress Now; as to the second problem. Recall that I did not set up a narrow negotiation for my second SCSI drive (an older micropolis drive.) This worked fine for 2.1.6.1. However, with 2.1.7, I have to disable (in the Adaptec BIOS utilities) WIDE negotiation on this drive or FreeBSD doesn't see it (an aborted command is all the probe prints.) Again; this is new with 2.1.7.xxx For info - I've appended the front part of the probe (as taken from dmesg). So - it looks like things got worse for my particular situation in 2.1.7.1.... - Dave Rivers - FreeBSD 2.1.7.1-RELEASE #0: Thu Mar 20 20:22:54 EST 1997 rivers@lakes.water.net:/usr/src/sys-2.1.7.1/compile/LAKES CPU: 133-MHz Pentium 735\\90 or 815\\100 (Pentium-class CPU) Origin = "GenuineIntel" Id = 0x52c Stepping=12 Features=0x1bf real memory = 33554432 (32768K bytes) avail memory = 30457856 (29744K bytes) Probing for devices on PCI bus 0: chip0 rev 1 on pci0:0 chip1 rev 1 on pci0:7:0 chip2 rev 0 on pci0:7:1 ahc0 rev 0 int a irq 15 on pci0:17 ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs ahc0 waiting for scsi devices to settle (ahc0:0:0): "HP C3323-300 4242" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 1003MB (2056008 512 byte sectors) (ahc0:1:0): "MICROP 1548-15MZ1077802 HZ2P" type 0 fixed SCSI 1 sd1(ahc0:1:0): Direct-Access 1635MB (3349512 512 byte sectors) (ahc0:2:0): "WANGTEK 5150ES SCSI FA23 08" type 1 removable SCSI 1 st0(ahc0:2:0): Sequential-Access drive offline (ahc0:3:0): "NEC CD-ROM DRIVE:400 1.0" type 5 removable SCSI 2 cd0(ahc0:3:0): CD-ROM cd present.[217422 x 2048 byte records] vga0 rev 211 int a irq 11 on pci0:20 Probing for devices on the ISA bus:
