Yes! Just in time! Thanks, S=F8ren :-)
Using kernel from RELENG_5, supped yesterday.
Tried to install on in a box with a Promise TX 2200 card, the bootup=20
took forever, but the install worked fine when it finished.
Maby related to the third "phantom" PATA bus on that board? :-)
I'm installing from network (PXE) and for some reason I don't get any=20
kernel messages on the console when doing that, so I don't know when or=20=
where it 'hangs'.
I forgot to copy in my modified kernel after the install, so I never=20
got it booting after that, but I'll redo as soon as possible and get=20
back with more details about this.

This works with my Intel S875WP1-E with Intel ICH5 / Adaptec HostRAID=20
onboard!
(The product specs says Promise controller, but that is only when you=20
buy the 4-ch SATA version)
However, if I create a RAID1 array in "Quick Mode", installation failes=20=
with write errors ("disk full"). The Adaptec management BIOS warns=20
about creating arrays in Quick Mode, so this may be a problem of=20
theirs.
Anyway, is there any way to detect that an array is created in this=20
way, and handle it, or warn about it?
The warning message from the BIOS says "You may need to repair the=20
array once OS is installed" or similar, so the array probably should be=20=
marked DEGRADED, and be rebuilded once the installation is finished.
I can no longer use my swap partition as dump device:
# dumpon /dev/ar0s1b
dumpon: ioctl(DIOCSKERNELDUMP): Operation not supported by device
But I'm not certain that it has ever been allowed? :-)
Maybe it won't work to have dump device on RAID, since the kernel won't=20=
be able to keep the RAID in shape when it's dumping core?
I have not done any extensive testing yet. I'll get these boxes=20
installed and set up various tests to see how it performs. I'll also do=20=
some hotswap testing on the TX2200.

I most certainly will! Thanks.
