Hi,
i'm using on the machine kernel 2.6.0-test6-mm1 and 15 IDE Drives. Everything worked fine (uptime about 30 days)
I used, some raid5's, below some raid0's and on top evms.
heres "cat /proc/mdstat" so its more clear
============ cut
Personalities : [raid0] [raid5]
md4 : active raid5 hdp[2] hdo[1] hdn[0]
120627072 blocks level 5, 32k chunk, algorithm 2 [4/3] [UUU_]
md3 : active raid0 hdm[1] hdl[0]
49956352 blocks 32k chunks
md0 : inactive hdc[0]
80418176 blocks
unused devices: <none>
============ cut
here are some drives missig,
md0, is one drive missing
md1, complete
md2, also
when i make a "evms_activate" i get

You should only remove this PV if you know the PV will *NEVER* be available again. If you think it is just temporarily missing, do not remove it from the container.evms_activate: Responding with default selection "Don't Remove".
LvmRegMgr: Would you like to fix the metadata for container lvm/rubbish?
evms_activate: Responding with default selection "Don't Fix".
LvmRegMgr: Region lvm/rubbish/basket has an incomplete LE map.

========= CUT
or in other words, its a mess. I verfied, all drives are found and work correct, so its "only" the meta information which is broken, i uses evmsgui to configure the whole thing, so there is no raidtab file, which i could use to force the configuration.
I also tried newer Kernel versions, but there is a timing problem i think, i use promise ide-pci controllers, and the new test9 always tries to reset those with UDMA(i think so), which won't work with that many drives.
So, is there someone who can help me ?

This isn't too unusual; if as you say the drives are fine then I'd agree
it is probably a controller issue. I've got a RAID that does this
regularly and you normally find in the log somewhere an IDE error of
some type (typically it dropping out of DMA due to a busy or it not
responding).
I've given up using multiple IDE PCI cards for this - they only just
work, and occasionally you'll get a glitch like this. I've tried
a mixture of Promise and HPT cards. In the end I gave up and got
a 3ware IDE RAID card which is working fine (you could just use it
as a large multichannel IDE card and run soft raid if you want I think).
