In this case there's only one harddisk and when I do # atacontrol mode 0 UDMA66 BIOSPIO
I get lots of such lines:
ad0: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=20185375 ad0: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=20185375 ad0: FAILURE - WRITE_DMA status=51<READY,DSC,ERROR> error=84<ICRC,ABORTED> LBA=20185375
I am wondering if building a kernel with the various debugging options turned on might help (see the developers handbook). If you can get a dump or trace then there is a good chance that one of the FreeBSD hackers on this list or -bugs can sort it!
Transfer rates:
outside: 102400 kbytes in 19.370328 sec
= 5286 kbytes/sec
middle: 102400 kbytes in 19.378847 sec
= 5284 kbytes/sec
inside: 102400 kbytes in 19.379687 sec
= 5284 kbytes/sec
Pretty low transfer rates, clearly not UDMA66!
best wishes
