Hi All, [please keep the infra-private list in the replies] We've recently attached a external JBOD, Storform D53J, to a dell pe 2950 via PCI-e cards (using the mpt driver). This works fine on stable/7@r197719 [1] despite being before some mfc's of mptutil work from scottl. When booting stable/8@204185 the boot hangs [2] Whats more, is if we disconnect the array physically, we're able to boot [3] the stable/8 kernel and even use the array from a chroot'ed install of the stable/8 userland [sudo camcontrol rescan all, and some zpool stuff] We've already seen this suggestion on google /boot/loader.conf: hw.pci.mcfg=0 which didn't help. Additionally, the following pr might be relevant but we haven't tried it yet. http://people.freebsd.org/~linimon/studies/prs/prs_for_tag_regression.html http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/142263 disabling acpi Thoughts ?
