We actually tried this, although using sol10-version of mpt-driver. Surprisingly it didn't work :-)

What's the earliest build someone has seen this problem? i.e. if we binary chop, has anyone seen it in b118? I have no idea if the old mpt drivers will work on a new kernel... But if someone wants to try... Something like the following should work... # first, I would work out of a test BE in case you # mess something up. beadm create test-be beadm activate test-be reboot # assuming your lasted BE is call snv127, mount it and backup # the stock mpt driver and conf file. beadm mount snv127 /mnt cp /mnt/kernel/drv/mpt.conf /mnt/kernel/drv/mpt.conf.orig cp /mnt/kernel/drv/amd64/mpt /mnt/kernel/drv/amd64/mpt.orig # see what builds are out there... pkg search /kernel/drv/amd64/mpt # There's probably an easier way to do this... # grab an older mpt. This will take a while since it's # not in it's own package and ckr has some dependencies # so it will pull in a bunch of other packages. # change out 118 with the build you want to grab. mkdir /tmp/mpt pkg image-create -f -F -a opensolaris.org=http://pkg.opensolaris.org/dev /tmp/mpt pkg -R /tmp/mpt/ install sunw...@0.5.11-0.118 cp /tmp/mpt/kernel/drv/mpt.conf /mnt/kernel/drv/mpt.conf cp /tmp/mpt/kernel/drv/amd64/mpt /mnt/kernel/drv/amd64/mpt rm -rf /tmp/mpt/ bootadm update-archive -R /mnt MRJ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
