I solved it by adding hint.atkbdc.0.disabled="1". As I wrote before, 'it would be nice', if such fantom devices could be detected at boot time, so the same fs/root/kernel could work on 'similar' platforms out-of-the-box. with the kbd, i found where it was looping, in 'atkbdc.c: empty_both_buffers', but got lost trying to figure out how to get out of it (specialy since there is no kbd/buffer :-). danny ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

That doesn't happen with parent devices not supporting hwtagging. And this totally excludes possibility to run a bridge over vlans with parent device which support hwtaggs. And something else was observed with re driver - it is impossible to disable hwtaggs by -vlanhwtag neither you can disable vlan mtu :).

Create a mirror, than partition a mirror provider. Is this a constraint in the design? Im my point of view, geom would treat all block devices equally, no matter if they are whole disks or single partitions. If this is not the case, them maybe this should be noted in the man page. Note that sometimes it is not necessary to have a whole disk redundant. I could use part of it to temporary data, for example. I've done this with vinum in 4-stable more than once: I get two disks, each with a copy of the root partition (which I intended to mirror with gmirror), a swap partition, a mirror vinum subdisk and a stripe vinum subdisk. Note that in this case the data integrity and cost is more important than continuous operation. If a disk fail, the server will stop, but no *important* data will get lost. This is the scenario which I was testing. +> Now, lets reboot. I could not unload geom_mirror, since it was +> preloaded during boot, is this expected?

Before putting it in /boot/loader.conf, unload worked, even with mirror devices configured, IIRC. Only after loader.conf preloading this problem appeared. +> Ok, now let's try something diferent.

Gmirror uses the last provider's sector for metadata. If two or more providers share the same last sector (as in your case), use '-h' option. The man page says only: -h Hardcode providers' names in metadata. and does not explain when I should use this. Do you mean that if I want it to use ad1s1 as the provider, and not ad1, -h is what I want? I do not have access to the test machine right now, will try tomorrow morning. +> Is there any gmirror hacker around to fix these? There is nothing to fix. Surely there is. At least the manual. And even if gmirror is correct, there's also the problem shown with disklabel in my previous email.
