Hello everyone,

I'm using Azimutz's compiled bins, and I'm having no luck with mem detection. It hangs right after spd detection indefinitely, which it gets wrong anyway. With memdetect off I can boot into the system fine.
The point where it hangs is in scan_mem() right after the call to scan_dram_controller, so the culprits are one of these two

scan_memory(&Platform); // unfortunately still necesary for some comp where spd cant read correct speed
scan_spd(&Platform);

Unfortunately none have any usable logging so I can't figure out which one is the culprit.

I have an Acer Travelmate 5720, with DSDT fixes applied. Has anyone else with a similar-ish system had any success with mem detect?

Thanks!

Does the same happen with the RC5 from Chameleon's trunk also? as that's the main stable build.

Hi, thanks for the reply, I haven't attempted to use the main trunk ones, as I couldn't find binaries anywhere, would you mind pointing me to the right direction?

No problem - see attached. I've just built this from the current trunk - r668

Thanks again :) replaced /boot , version string on bootup is 693, mem detection freezes up at the same spot.

Thanks for checking it again. I had to know whether or not your issue was specific to Azimutz's branch or not. Unfortunately, I can't help you fix the problem in the code but I can give you two possible routes to progress with for now.

1) Disable automatic memory detection as you have, and add your memory details in to your /Extra/SMBIOS.plist.  You can find more information at Gringo's 'How to configure /Extra/smbios.plist' post.
2) Post this issue at the repo and hopefully a developer will see it. LINK.

I'll also move this topic to bug reports.
