GA-P55M-UD2 i7 860 K Panics after 24 hr shut down

[homesnake]

hey guys I need a bit of advice tackling this problem. My machine KP's after being started. This is after it has been fully powered down for the night (NOT deep sleep).

It starts fine
It deep sleeps fine
It powers down fine

On restart afer 24 hours? KP:

the KP error msg above might have a few garbled lines, I had to copy it from a camera phone - but it is 95% accurate

As I try to troubleshoot this and a couple things that are confusing me,

this occurs on two different disks, one with 10.6.2, the other with 10.6.3

I combed through the BIOS it seems like a hundred times and it seems to be set up correctly.

???

I am sort of thinking maybe the DSDT is the issue, I have tried a few different ones with the 10.6.2 install but have stuck with default multibeast for the 10.6.3 install.

If anyone can decipher what the KP is pointing at specifically I would really appreciate the knowledge. I saw "mkext archive error" bit so I rebuild the mkext a few different times with kext utility and multibeast, but that didn't seem to help.

My kexts in E/E are: fakesmc, JMicronATA.kext (on the 10.6.2 disk) and fakesmc and JMicron36xATA, and JMicron36eSATA (on the 10.6.3 disk)

I haven't tried setting the boot.plist to 32 bit, but will try tonight.

PPS I'm 98% there - this is going to be a great machine thanks to all the smart folks here.

What files do you have in /extra/extensions and /extra?

 

[homesnake]

well this kernel panic was on the 10.6.3, where I have:

fakesmc
JMicron36xATA
JMicron36eSATA

in the E/E folder

I booted the machine up this morning (into the 10.6.3 disk just mentioned) and got another KP, so I tried booting into the older 10.6.2 install where I had the added the 32 bit flag and it booted up fine.

I will have to test during the week to see if the 32bit mode will allow at least 10.6.2 to boot consistently.

EDIT: the extensions on the 10.6.2 disk that just booted up were

fakesmc
JMicronATA.kext

ha, well, things went from bad to worse, system started to become unstable after about 10 - 15 minutes use. Decided to reinstall following all the new iboot/multibeast steps.

I am guessing it was something I did wrong, hopefully the fresh install will work better.

 

[adamsmasher]

That's probably a good idea- given the hardware that you listed, you shouldn't be having any major problems like. Do you have any other hardware besides what's listed in your sig? Reading and writing to any NTFS partitions?

 

[homesnake]

I have a windows 7 partition though it isn't connected, oddly when I had it connected it showed up as two different partitions, one "system reserved" and the other "windows NTFS" in the chameleon menu. It has been disconnected for the last few days just to help me troubleshoot, could it have caused these issues?

anyways I did a fresh 10.6.3 reinstall using the a la carte options along with tony's speedstep i7 860 DSDT and and so far so good. No panics, have done quite a few restarts and no problems (other than the known/documented issues like USB etc).

oh also I fixed permissions using disk utility and I had no errors, which is probably a good sign.

really hoping it boots up without issue tomorrow morning!

 

[homesnake]

bummer - it KP'd again this morning.

back to the drawring board

 

[adamsmasher]

Do you have a wireless card or PS/2 devices? Which USB ports are you using?

 

[homesnake]

no wireless, no PS2 or anything weird at all.

I did go out and get a fresh hard drive today however, a WD 500G. The disks I had been using were an older 80G SATA drive and a Kingston 64GB SSD drive. I kinda doubt it was the media at fault, but then I had a pile of issues early on because I was using an older DVD drive to do the initial install (replaced since), so I figured I had better make sure I had a standard, reliable drive to start from.

With that out of the way I thought I had better try a more basic style of install, so I used the multibeast option for my UD2 board. Have that up and running, so I'll just wait until tomorrow and boot up to see what happens.

I guess the basic multibeast installs a DSDT without speedstep edits? my fans are running full blast and MSR tools doesn't show any info when I boot into 32 bit mode, but this point I am kinda getting anxious just to get a stable machine, speedstep be damned.

 

[adamsmasher]

I don't believe there are any edits to the DSDT for speedstep as you can get that using the iMac 11,1 smbios, and by enabling all the advanced CPU features in BIOS.
