I am having problems with RELENG_4 (cvsup last night) crashing. I recently purchased a WDC WD1600JB (160GB) disk drive to attach to my trusty, old home server: ASUS P5A-B Motherboard with integrated Acer UDMA33 controller Fujitsu MPC3032AT/6018 (3GB) disk drive (channel 0 master) FX322M/w03 CDROM drive (channel 0 slave) I presently have the WD1600JB was added as the channel 1 master (no slave). It is connected to the controller using the 80 conductor/40-pin cable provided with the drive. (I've also tried to setups with the WD1600JB replacing the CDROM drive as slave on channel 0, using both 80/40 and 40/40 cable with like results.) I have configured the BIOS (as directed in the WDC documents) for C/H/S for 1023/16/63 (528M). RELENG_4 sees that a UDMA100 drive is connected to ata1 and tries fallback to UDMA33 and then to PIO4. This is the last page of messages (which shows the panic). I'll try to type in more if this isn't enough (sorry, but I don't a laplink cable handy): ad2: trying fallback to PIO mode ata1: resetting devices .. done Fatal trap 12: page fault while in kernel mode fault virtual address = 0x78007a fault code = supervisor read, page not present instruction pointer = 0x8:0xc018760e stack pointer = 0x10:0xc03b9314 frame pointer = 0x10:0xc02931c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = Idle interrupt mask = bio trap number = 12 panic: page fault This seems to be related problems others have noted with regards to Acer UDMA33 controller and RELENG_4. It does seem specific to 4.x as tests against 4.8 failed same as above yet tests against FreeBSD 5.2 and NetBSD 1.6 were okay. Kurt
