I don't have any solutions for you, but I'm curious to know what kind of
drives you're using... apparently SiI 3114s aren't so good with bridged
(PATA<->SATA) connections, and Seagates are mostly native...
On my setup (SiI3112+Seagate), I get WRITE_DMA timeo's a few times a
day. Never had panics as result of the SATA tho.
atapci1@pci0:13:0: class=0x018001 card=0x02509005 chip=0x31121095
rev=0x02 hdr=0x00
vendor = 'Silicon Image Inc (Was: CMD Technology Inc)'
device = 'SiI 3112 SATARaid Controller'
class = mass storage
ATA channel 2:
Master: ad4 <ST3120026AS/3.18> ATA/ATAPI rev 6
Slave: no device present
I don't even use it very heavily, it's *just* for my .oggs. Nothing
else. It sucks. We're presently looking at 3Ware and others for a heavy
duty network setup we're doing... hoping we can make the SiIs work
instead of dropping a few grand on 3Wares... :\ but I'm not confident
the SiIs are good for anything important.
