I get completely flooded...
I get the debug output 2 times (ide0 and ide1 maybe?): the first time it
stops after a few 100 lines and driver init continues a bit, but the
second time it just goes on and on and eventually I decided to reset the
box.

Should this be >=32 maybe?
If you really do want the to skip the first 32 and capture the rest, I can
still get it, but I'd have to split the printk as it's too wide for my
serial console so part gets truncated.

This is what I could get from the *second* series:
IDE-DEBUG: host->host_flags[0x10] hwif(fffff8003e326800)
host->cur_port((null))
hwif->port_ops(cmd648_port_ops+0x0/0xfffffffffffffe54 [cmd64x])
hwif->hand
Rest is truncated. This first part seemed constant.
