I fixed it. Now calibrates to 1038mv and working great.

In opp4xxx_data.c -
Code:
    /* SGX OPP1 - OPP50 */
    OPP_INITIALIZER("gpu", "dpll_per_m7x2_ck", "core", true, 153600000, OMAP4460_VDD_CORE_OPP50_UV),
    /* SGX OPP2 - OPP100 */
    OPP_INITIALIZER("gpu", "dpll_per_m7x2_ck", "core", true, 307200000, OMAP4460_VDD_CORE_OPP100_UV),
    /* SGX OPP3 - OPPOV */
#ifdef CONFIG_OMAP_GPU_EXTRA_OVERCLOCK    
    OPP_INITIALIZER("gpu", "dpll_per_m7x2_ck", "core", true, 512000000, OMAP4460_VDD_CORE_OPP100_OV_UV),
#else
    OPP_INITIALIZER("gpu", "dpll_per_m7x2_ck", "core", true, 384000000, OMAP4460_VDD_CORE_OPP100_UV),
#endif
Basically changed the 384 to use OPP100_UV instead of OPP100_OV_UV

Been flashing every nightly since the hundred teens. Much love for this kernel, works well with the app.

Noticed some faster battery drain than normal with the past two nightlys, heres hoping 154 is back its legendary status

I posted earlier that the latest nightly was making my phone run hot. It seems i posted a lil hastily. Now the phone runs much cooler, it barely get over 120 degrees with heavy use like loading 5 consecutive websites. Maybe i didnt give the kernel time to settle in properly. Im running ondemand 192-1228 no hotplug. Earlier i was running interactive with the same freq and no hotplug, will test batt life tomorrow. Thanks for the killer kernel, franc tha tank!

Found something interesting... if you look in voltage.h in mach-omap2 you can see that the phone is limited to a minimum voltage of 830mv. When I lowered this to 700, SmartReflex calibrates my 384mhz frequency to 770mv instead of 830mv. Running just as stable as before.

yeah OV_UV is not needed until higher speeds
