I tried patch; I can mount partition from ATA drive without problems, but after
installer starts to extract installation sets kernel prints several error
messages (same error with lost interrupts when using wdc_mb.c without
ATAC_CAP_NOIRQ) and then reading seems to freeze.

As a side note: it seems that some of the latest patches (probably pmap sync)
cause FALCON kernel to freeze before kernel prints any messages with 68060
cpu. I used BOOTX to test things and it does not have this problem.
