Multiple Promise Ultra 100 TX2 controllers...

So, to summarize: two controllers work fine, three fail.
Have you turned on CONFIG_PDC202XX_BURST in your kernel config?
It is in the IDE/ATA section of the kernel config. It shows up in
menuconfig as "Special UDMA feature" and the help text says:
For PDC20246, PDC20262, PDC20265 and PDC20267 Ultra DMA chipsets. x
x Designed originally for PDC20246/Ultra33 that has BIOS setup x
x failures when using 3 or more cards. x
x Unknown for PDC20265/PDC20267 Ultra DMA 100. x
x Please read the comments at the top of drivers/ide/pdc202xx.c x
x If unsure, say N.
It sounds like it might help.
