Still trying to solve a creeping CPU kernel issue ( I don't have a power consumption issue ) what I have is a slow growth in kernel CPU use in an idle systems that eventually will freeze a system in a few weeks (or cause a dtrace run of say 'hotkernel' to freeze the system even earlier in about 20-30 hours).
The odd thing is I have the same MOBO X9SCA-F as you I have a E31270 CPU. I keep banging on the issue 148b, 151, 151a and even some new dev bits for acpica but I can not solve it. – Refer to illumos bug #1333
I am currious could you post the following (or E-mail it ot me)
uname -a
top -b | head -15
rup `hostname`

/usr/sbin/prtdiag | head

BIOS rev (at boot if known)

After a few weeks of running, the benchmarks have improved slightly, which is interesting to me. Sequential writes are up almost double to 497 MB/s, sequential reads are roughly the same at 529 MB/s.

I’m very pleased so far, and still haven’t implemented read caching. With these performance numbers, a read cache may actually decrease performance on sequential reads, but should assist random reads somewhat, we’ll see what happens in practice.

Hi Jon, I haven’t noticed a power consumption issue but frankly I haven’t been watching it that closely. I will take a closer look and let you know if I see anything.

Do you have a power managment issue on this system I am runnign 148b on a X9SCA and have a slow growing CPU usage across time on this system it appears to be related to settings in the /etc/power.conf file I am using the following – but it doesn't totaly solve my issues.
cpupm enable poll-mode
After a few days the system uses 12.5% (one hyperthreded core ?) of my CPU.

Thanks in advance

I really like this guide it was super useful!
But I really wanna chaneg my kernal.
I followed the directions and going to do the same one as you did.
should i wipe data and cache as well as backup my existing rom? is that necessary for this?

Hey – you wouldn’t happen to have the spec for the F13 sensor would you? I’m hunting for it, but it seems to be hard to find

Comment on Sigma SD14 Saturation Problem by Paul Edson

Hello Jason, I saw your post after I recently encountered the same problem photographing red flowers in sunlight. ( Program mode/ISO 100/1.07 firmware.) Using Lightroom and Sigma’s PhotPro 3.2 for Mac, the photo’s are unrecoverable. MAcro shots under controlled light sources do not seem to exhibit the issue. I’m not sure if the camera sensor or firmware is the problem. Like your camera, my is still under warranty. Has Sigma made any effort to respond or correct?
