Hello,
did anyone have the opportunity to test operation with a MV88SX6081 SATA
controller on FreeBSD 8.0 ? My amd64 dual-Opteron (using 4G ECC RAM)
system just works fine with it on FreeBSD 7.2, but can't handle any
high-speed disk I/O when booting with a FreeBSD 8.0 kernel.
I have two controllers as follow :
atap...@pci0:17:4:0:class=0x01 card=0x11ab11ab chip=0x608111ab
rev=0x09 hdr=0x00
vendor = 'Marvell Semiconductor (Was: Galileo Technology Ltd)'
device = 'MV88SX6081 8-port SATA II PCI-X Controller'
class = mass storage
subclass = SCSI

On FreeBSD 8.0, attempting to scrub a ZFS pool results in a few I/O
bursts (confirmed with zpool iostat), before totally freezing down and
locking the ZFS pool (the system is still up and only ZFS based file
systems are unusable in this state), probably to avoid data corruption.
Occasionally I also witness a READ_DMA48 soft error (ECC corrected)
error message showing up, on a random hard disk.
I already gave the hard disks a thorough check and they work just fine.
On FreeBSD 7.2-STABLE, the scrub proceeds nicely and the I/O peaks at
300MB/s (confirmed with zpool iostat) on the pool without a hitch. I
could also confirm that attempts at booting a FreeBSD 8.0-RELEASE kernel
did not damage my ZFS pool checksums or anything.
Therefore, I am inclined to think the motherboard/memory (a TYAN
Thunder K8WE S2895) would be at fault here, and that something in
FreeBSD 8.0 brings out this very specific problem, but I would first
like to hear about any tests of the aforementioned controller on FreeBSD
8.0 on another environment before upgrading the hardware.
Thanks in advance for your time,
P.S. : Here is the dmesg trace for FreeBSD 8.0.
