Well.. i seem to have no problem with my sd card mount. i also didn't follow the exact flash procedure as reccomended in the first post
-wipe data/factory reset
-mounts and storage>-format boot
-advanced>wipe dalvik cache (no i didn't use the dalvik wiper just plain ol' good clockworkmod option)
After that just flashed the rom, boot up, i then did absolutely nothing, just left it in the launcher and 5-10 mins later i made a reboot, normal reboot not recovery.
Again i just left it there for a while.
After that i booted to recovery, wipe cache/dalvik cache and then flashed the kernel i wanted (matr1x).
Boot..and then i got to work, system settings, not anything really on the performance, it isn't needed at all, and then restore all the apps i wanted with a batch backup tool
, that i've mentioned before and.. reboot..
Well the point here is that have a pretty good battery life (around 2% loss per hour when idle) and a completely stable device. I've yet to see any of these bugs that have been mentioned. i even restored some systen app data with Tiatanium Backup and everything went smoothly
My device is an i9023, although i don't think i really matters (although it may do..but it's unprobable)
