I didn't have any filesystems mounted but learned that the 4 disks
participate in a md raid5 set. To be sure I tried everything again from 
the beginning (reboot) without enabling md on the four drives. Here are 
the results:

1. started the four dd processes which ran to completion without any 
errors. Started them again and this time sda failed as usual.

2. modprobe -r sata_promise - no warnings/errors: removed successfully

3. modprobe sata_promise - only three drives show up

4. modprobe -r sata_promise - no warnings/errors: removed successfully

5. modprobe sata_promise - more channels complain - no drives are found

dmesg:
