We have a Dell SC1435 with the above SATA controller which was running
FreeBSD6.2 fine for about 3 months.
We re-built it with FreeBSD 7.0-RELEASE from scratch (ie complete new
install from CD). Installation failed while copying base system from CD
Suspecting a possible hardware issue we rebuilt it again with FreeBSD
6.3. It built and ran fine, thereby eliminating any hardware problems.
Repeated attempts of installing FBSD7.0-RELEASE continued to fail at
slightly different points, but always when writing to disk. Virtual
Console 2 showed the following errors:
NMI ISA 20 EISA
ad4: TIMEOUT WRITE_DMA
aNMI ISA 20, EISA
FAILURE - WRITE_DMA. retrying
I suspect this is related to other (S)ATA related problems which have
been reported on this list, eg:
I would be happy to provide more information to help debug this problem,
however it is slightly difficult as I cannot even get the system
installed under 7.0.
Any suggestions on how to get better info. I could also look into
providing remote access to the machine.
