Hello to all;
I had a MSI mobo 645 Ultra with 1.5G ram, pentium 4 1.7 Ghz, 3 IDE HD, 1
SAMSUNG 80 G, 1 SAMSUNG 120 G, maxtor 120 G and a LG DVD writer. FreeBSD 6.2
recognized all HDs as ultraDMA 100. Fine.
Then a bought a ASUS p5vd2-x, 1G ram, Gforce 7200 video(pci-e), pentium D 940
Dual core and kept the same drives. After tuning and recompiling the kernel
a couple times, I got almost everything working great ! SMP, acpi, network,
you name it, EXCEPT ultraDMA.
if I leave:
hw.ata.atapi_dma: 1
hw.ata.ata_dma: 1
FreeBSD reports them (all) at ultraDMA 33. The system boots ok but after 7 or
10 minutes (even if doing nothing), I start geting messages from
g_vfs_xxxx(); WRITE DMAERROR that can come from any of the drives until the
system becomes unstable and ends up rebooting itself.
if I leave:
hw.ata.atapi_dma: 0
hw.ata.ata_dma: 0
The HDs get down to PIO 4 and the system works fine but at an incredible
performance cost.
Finacial issues force me to make this work instead of buying more stuff.
Thanks for any suggestions,
Sorry, i that should be
atacontrol cap <device>
not
atacontrol info <device>
