More apologies as I'm not overly familiar with the bootup sequence, and have probably got some terms wrong.) Basically, I'm finding that the 8.1 and 8.2 kernels hang on certain machines during bootup, specifically during device discover and module load. I've tried 8.2 off the current release CD, and also 8.1 off the Debian kfreebsd 6.0.0 distribution - both have the same issue. Basically, the console gets as far as the messages ... acd0: DVDR ...... at ata1-master UDMA66 uhub0: 3 ports with 6 removable, self powered uhub1: 3 ports with 6 removable, self powered uhub2: 6 ports with 6 removable, self powered and there it hangs. If I run the boot in 'single step' mode (set boot_pause, set boot_verbose), I find the one machine hangs consistently. The screen shows at the bottom the text fwip0: Firewire address: ...... maxrec 2048 fwohci0: Initiate bus reset fwohci0: fwohci_intr_core: BUS reset fwohci0: fwohci_intr_core: node_id=0x00000000, SelfID Count=1 CYCLEMASTER mode pcib2: at device 30.0 on pci0 fwohci0: fwohci_intr_core: BUS reset and that's it. Dead as a dodo. (Can't check the other machine - it's the one I'm typing this on :-) OTOH if I disable usb and floppy in the bios, and do a 'boot -v', the messages stop after ata5: Identifying devices.... ata5: New devices 00000000 ATA pseudoRAID loaded flowtable cleaner started WHile a 'boot -v -p' reaches instead lines about atkbdc0, then atkbd0 and finally atkbd: the current kbd controller command byte 0047 before hanging. It suggests to me the final line shown is not particularly related to the lockup, but that something else is happening behind the scenes. Out of 4 machines I've tried this on, it hangs on two, and boots OK on two. The OK ones are an acer laptop and a machine with IIRC an SiS chipset - both machines that it fails on are (different) nf7s mobos, and also have floppy (but disabling this does not fix the problem, it might be changing the exact message though) and firewire (can't remove or disable). I'm at rather a loss; I've found nothing on the net to suggest there's a general problem. I know an older version (6.2) of fbsd boots happily on all four of these machines; the two failing machines are currently running debian and dual-boot ubuntu/XP, so it's not a hardware fault as such. Any ideas please as to what's going on, or where best to look for more information? TIA. -- Mike Scott Harlow, Essex, England
