[Desire HD Android Development] DazzaL:
standard CPU setting (1ghz) here with smartass v2 and no undervolting. i get reboots every couple of days on average, for some time too. also I log all my last kernel messages on reboot and have always seen the same stack trace in every single reboot ive ever had (i've reported this before in the Q&A thread too).

eg http://pastebin.com/7iNU1cTB

my last lot of reboots:

ive not flasted 8.0 test 1 yet, but had 1 OOPS on 8.0 final too.

not sure if it will help me but ive just tried this (only yesterday so too early to tell)

root@android:/data/kmsgs # sysctl -p

sysctl -p

vm.dirty_ratio = 90

vm.dirty_background_ratio = 55

vm.vfs_cache_pressure = 20

vm.oom_kill_allocating_task = 0

vm.min_free_kbytes = 2048

vm.swappiness = 0

kernel.panic_on_oops = 0 <-- set this to see if it stops the web core thread problem taking out my whole phone.

root@android:/data/kmsgs #

also as a side note i suffered occasionally (esp during games) with stuttering, sometimes really bad. during this time i observed, in nearly all cases that kswapd0 was chomping up the CPU. I cronned a renice script every 5 minutes and not experienced random lagging since (been stable for a few weeks now). i havent tried disabling it the new 8.0 to see if the problem no longer occurs so it may not be problem any more.

note: always wiped /system and full wiped too on the last test version I used.
