[Samsung Galaxy Nexus] 7175:
Did you enable/disable wifi, could be hang? Try killing market, clearing market data/cache, reboot, then try wiping dalvik/cache in recovery, reboot. If you have gapps package handy you could try flashing it in case Play files broke. Before that, definitely try flashing another kernel with 3.3 wifi drivers, since these wifi drivers are still new. Could just be wifi hang though.

On another note, really liking the new AK-pirates-704 and getting some awesome battery life. I've always liked the way smartReflex works on AK, so I decided to run some experiments with SmartReflex using custom input voltages and see how voltage calibration varied over stock. I ended up coming up with some good values for MPU input to minimize SR-calibrated voltages and ended up just leaving CORE, IVA stock. Changing CORE and IVA voltages for SR-calibration or with SR-OFF only lead to system instability yet again. The SR-calibration with CORE and IVA using stock values for maximum voltage works really well already.

I keep information typed in notepad++ to keep track, so in case anyone's interested or may find this helpful at some point, I'll post some results I got below from the 704 kernel. After finding optimum SR-MPU voltages and changing a few kernel settings, I've been getting really good battery life, over 6 hours of screen time draining the battery from 100% to automatic shutdown. I still need to check idle. It would be really useful to increase idle battery life by a lot if there was a kernel [[option for MPU_min_screen_on like fancy kernel has implemented so that frequency can drop to 180-230 screen off and stay at 350 min with screen. I did some basic benchmark tests with Antutu and Quadrant to check IO/read/write scores for different IO schedulers/1024readahead: stock-fiops, bfq, fifo, row, deadline, SIO, and VR. SIO and fiops come out on top marginally better than others over multiple tests. fiops runs really well with low readahead 256 though, SIO was best at 1024-2048, so I would stick with fiops.]] With MPU_max at 1200MHz & 1640MHz, I've been getting Quadrant scores total: 3200 & 4000; CPU: 5700 & 7900; and I/O: 5100 & 6500. Gotta love fiops I/O scheduler, Fair Flash I/O Ops Per Second.

:good: :good: :good: for pirates-704. :)

/*SR voltages are sensitive to user input values; large calculation fluctuations
occur (can be seen in measured values) even with 1mV changes to user
input values for CORE, IVA, and MPU. For CORE, set V1=V2; if V1!=V2,
whichever one gives a higher SR voltage seems to set it for both V1 & V2.
SR calculations for CORE, IVA, and MPU also seem dependent on CORE
user input values. I tweaked CORE values by adding +/- 10 to stock values,
1mv at a time, and checked measured CORE and MPU voltages to optimize.
I ended up leaving CORE and IVA values alone, and only settings MPU values
to give optimum calibration. */
