i lent a hpt366 from a friend
and tried things out (found the uniform ide patch)
but when trying to make a raid0 of 4 disks (2 on piix and 2 on hpt366)
the machine justs crashes when executing mke2fs on /dev/md0 (just after a
few seconds)
when i recompile a kernel with default no dma on, it goes ok, but i get
worse performance. (about 4mb/sec on /dev/md0 vs about 40mb/sec with dma
on)
So i suspect the PIIX conflicts some way with the HPT366
I want to buy tomorrow a extra controller card, but what is the best
choice ?
a promise or a hpt366 ?
and i think to buy 2 of them (so 2* promise or 2*hpt366)
so i get the best change of no conflicts and best performance

i want to use the kernels that works best here ;-)
