I managed to get el capitan running fine last night, then this morning when I tried to boot I started getting ' P-State Stepper Error 18' error. Odd as I wasn't having this problem before.
My BIOS (f10) doesn't appear to have a setting for EIST, so unable to do the fix in list of solutions, however I changed system profile from MacPro 3,1 to iMac 13,1 as suggested in one of the comments - and this worked in as far as I was able boot into el capitan and everything looked fine.. However after about 30 seconds computer crashes and restarts without warning.
Rolling back to my Yosemite backup for now, but any thoughts on how this might be resolved would be appreciated!
