Verbose suggests it completes the scan of the PCI to LPC Bridge and PCI to PCI bridge. Comparing with a working verbose boot, the next stage, which isn't reached, is HyperTransport Technology Configuration. Trying BUS_DEBUG, I got a lot of this: device_add_child_ordered: 1813: (null) at pci with orer 0 as unit -1 make_device: 1698: (null) at pci as unit -1 I neglected to say before: the machine's been running FreeBSD 7-STABLE quite happily with no problems. - Harry On 28 February 2012 20:08, Ian Lepore wrote= : > On Tue, 2012-02-28 at 19:15 +0000, Harry Newton wrote: >> 9-RELEASE works fine. csup to 9-STABLE and make buildworld kernel etc >> gives a system the hangs during the boot process.
