I am really impressed with clover, testing on my T3500 with smbios macpro 5,1 and Xeon W3680, Geforce GT640.
The only thing I cant get past is: shutdown results in a KP and an instant restart (and wake up from sleep takes very long).
I have tried various Bios settings, and clover settings: darkwake, Hpet edits, Fake id, inject reset values and so on.
Even tried removing Tymce...kext and using smbios for Macpro 3,1 which also boots fine but same thing on shutdown.
Also edited AGPM kext for G-states but it did not change...
HPET, LPC, RTC, AICPUPM CPU PM states 111122 etc., everything seems to load fine.
Clover boots into OSX 10.10.1 all the time... but on shutdown I always get this KP after cpu is killed - something related to NV/Graphics. (Also of note the power button does not invoke the shutdown menu, only does full shutdown after a few seconds)
Can anybody tell me where to look further: clover settings/Bios or DSDT...? (see attached DSDT dsdt_config.zip 10.12KB 2 downloads and config)
