May be solved; sorry, only posted a question to the List on 12/03/2010
and forgot to add to PR. Below the Text:
Hi,
a while ago I created PR amd64/135040 because of Problems caused by the
SB600 on my MB not being 64bit capable (disk not being detected, disk
corruption after buildworld/buildkernel). Since then I lived with "set
hw.physmem=4gb" in my loader.conf.
The other day I found a BIOS-Update for my MB with the Note "Update PCIE
Initial Code". I did install the new BIOS, installed 8.1 from USB-Stick
to a "new" Harddisk, booted off that disk, csupped Sources, ran
buildworld buildkernel installworld installkernel, rebooted, ran built
and installed again, ...
The System did all this fine; disk was always being detected, no data
corruption, fsck ran w/o problems.
However, I'd be more confident -before removing set "set hw.physmem" and
run with "complete memory" off my "Production Disk"- if there was a way
to check, if the SB600 is really doing it's DMA correctly now (or was
the Driver changed to not do DMA on SB600?) - or if, by some
coincidence, the error did not show up during my "tests" but still
might/will occur.
Is there a way to definitely check if the Disk-DMA is really capable of
64bit DMA?
Would be cool if there was a way to check this...
MTIA, Cheers,
_ralf_
