Hi
this was solved since some date on releng_6 to beta2 but now it is here aga=
in

there is not even a disk on the second bus ahd1 and ahd0 is for sure a U320=
=20
(MB) disk which on beta2 still appeared as 320 but now as 160MB/s=20


camcontrol also shows different speeds where they should be the same even i=
f=20
wrong

res# camcontrol negotiate da0 -U
Current Parameters:
(pass0:ahd0:0:1:0): sync parameter: 8
(pass0:ahd0:0:1:0): frequency: 160.000MHz <<<<<<<<<<<
(pass0:ahd0:0:1:0): offset: 254
(pass0:ahd0:0:1:0): bus width: 16 bits
(pass0:ahd0:0:1:0): disconnection is enabled
(pass0:ahd0:0:1:0): tagged queueing is enabled

res# camcontrol negotiate da0 -c
Current Parameters:
(pass0:ahd0:0:1:0): sync parameter: 9
(pass0:ahd0:0:1:0): frequency: 80.000MHz <<<<<<<<<
(pass0:ahd0:0:1:0): offset: 63
(pass0:ahd0:0:1:0): bus width: 16 bits
(pass0:ahd0:0:1:0): disconnection is enabled
(pass0:ahd0:0:1:0): tagged queueing is enabled

This I get for beta2 on the same hardware

res# camcontrol negotiate da0 -U
Current Parameters:
(pass0:mpt0:0:0:0): sync parameter: 8
(pass0:mpt0:0:0:0): frequency: 160.000MHz
(pass0:mpt0:0:0:0): offset: 127
(pass0:mpt0:0:0:0): bus width: 16 bits
(pass0:mpt0:0:0:0): disconnection is enabled
(pass0:mpt0:0:0:0): tagged queueing is enabled
res# camcontrol negotiate da0 -c
Current Parameters:
(pass0:mpt0:0:0:0): sync parameter: 8
(pass0:mpt0:0:0:0): frequency: 160.000MHz
(pass0:mpt0:0:0:0): offset: 127
(pass0:mpt0:0:0:0): bus width: 16 bits
(pass0:mpt0:0:0:0): disconnection is enabled
(pass0:mpt0:0:0:0): tagged queueing is enabled

and dmesg shows
da0: 320.000MB/s transfers (160.000MHz, offset 127, 16bit)


following is beta3 dmesg:
