Please give us feedback with respect to how the si3124 driver works
for you.
I have a pair of si3132 based cards on a Tyan K8E motherboard, and
unfortunately, I am seeing what look like command timeouts with the
b59 si3124 driver. With an iostat running in the background, I get
something like this for about a minute each time:
extended device statistics
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device
0.0 0.0 0.0 0.0 3.0 1.0 0.0 0.0 100 100 c9t1d0
It happens almost immediately when copying a sizable file between SMB
shares of the same pool, though also more rarely when doing local I/O.
I have never encountered it with read only I/O patterns.
Also, the performance seems to vary widely. In general though, it
feels a bit more sluggish than the nForce4 SATA, and a scrub of the
pool took significantly longer.
I kind of wonder if there isn't something funny with the interrupt
setup, as I also occasionally get long delays with a USB key. That
said though, it is basically the same board as in the Ultra 20, so I
expected it would work well. (and, those two issues aside, it has
been quite solid.)
