Re: SiI3112 DMA? (2.6.0-test6)

So SiImage is cooperating with you on getting the SATA driver right? I've
been holding out on updating the kernel (I could probably extract the driver
diffs, but whatever) since experiencing data corruption/lockups on my SiImage
controller. If we can expect reliable, fast performance with this
controller soon, thats great news : )

I have a scheduled fix prepared for release and review by SiI monday
morning 9AM Pacific time. Once it is cleared by SiI, it will be released
out to the masses.

I can only chortle over the issue of how attempts to replace me, and me
trying to escape the indenture servant slave of maintainership yet still
bound after nearly 6 years.

Will attempt to address the mod15b phy issues

I'm having the same problems and I'm using the ol' 2.4.20-20.9 kernel
with RH 9. I had to give up on my Serial to IDE convertor so now I'm
using IDE again (I couldn't stand the 1.3 MB/sec transfer rate with the
SiI3112 so I reinstalled using IDE). Anyway, I too am looking for a fix
for this but it looks to me like very little if anything has changed
since 2.4.x. My system also crashes (to say the least! I lose all access
to my HD) when I try hdparm -X66 -d1 /dev/hdg.
