The forum doesn't allow me to post on that thread. and it doesn't allow me to send private message. I am getting very frustrated!
Below is my original message. Anybody please kindly forward it to the page. I am hoping it is useful for the devs.

Hi Cars,
I can't post to the thread (the forum doesn't welcome new users?).
Some fiddling suggests to look at the the block device IO / ext filesystem.
With CM11 0106(yours and the one on the first post) and 0105, I experience a lot of reboots / random FCs(like many others reported).
logcat records exceptions for writing files for FC'ed processes. Turns out /data is mounted ro.
In dmesg, I see a lot of block IO errors ( can't find superbloocks etc) in dmesg. /data is remounted io after these IO errors.
The hardware seems to be OK. I checked the devide (/dev/block/mmc0blk0p17) with dd, zeroing the entire partition / read out the entire partition to /dev/null in adb recovery (.5 version not the latest .6). no IO errors is reported durng these full-partition tests. Also no IO error with 10.1 (latest on your all cm thread, the one from last december).
Strongly pointing to block device/flash IO module. The difference in the kernel between recovery and the kernel in CM11 0106(all versions) or even maybe just the difference between 0106 and last reported working build(1225? I didn't test it) may help us to pin it down. What changes were in the upstream cm source between these dates?
Thanks for working on these roms!
