Last thursday I started getting error-messages like these whenever I
cvsupped or compiled something or du-ed: (Made the world from 4.6.2
to 4.7-stable as of the 6th of November (see dmesg at the bottom of
the mail).

etc., there's about 20 times as many for da0 as for da1.
# camcontrol devlist

(The cd-burner is on its own cable of course, spends its time
making backups.)
This machine runs my desktop and compiles kernels, worlds etc for
itself and the other freebsd-machines I have, which have less
memory and slower disks.
According to camcontrol and the verifier in bios there are no
new defects since the disks left the factory. No hardware has
been changed since sometime in early September so the cabling
haven't been touched. Prior to the makeworld the tags were at
their default 253, lowering them didn't improve matters.
Then these turned up today:
(da0:ahc0:0:0:0): parity error detected in Data-in phase. SEQADDR(0x56) SCSIRATE(0x93)
(da0:ahc0:0:0:0): parity error detected in Data-in phase. SEQADDR(0x8a) SCSIRATE(0x93)
(da0:ahc0:0:0:0): parity error detected in Data-in phase. SEQADDR(0x8a) SCSIRATE(0x93)
(da0:ahc0:0:0:0): READ(10). CDB: 28 0 0 8f df 22 0 0 70 0
(da0:ahc0:0:0:0): ABORTED COMMAND asc:48,0
(da0:ahc0:0:0:0): Initiator detected error message received
(da1:ahc0:0:1:0): parity error detected in Data-in phase. SEQADDR(0x8b) SCSIRATE(0x93)
etc.
The system is currently not particularly usable as things are coredumping
east and west; it can no longer tackle a make world.
If it is *only* a hardware-problem it is easy though expensive to fix;
but what part of the system is the problem? Cable, disks or controller-
card? In that case, what controller-card/disks would you recommend?
If it's something that was changed for 4.7, does it also exist in 5.x and
what other information do you need to have a look at it?
The motherboard is an Asus A7V and it's all been rock stable until now.
Here's the dmesg:
