Hi Aneesh,
Adding linaro-dev in the loop as someone else could be also interested
I have reproduced my thermal error with a lava test so you can have a complete log available here: http://validation.linaro.org/lava-server/scheduler/job/18564/log_file
As a summary of the problem, the panda board turns off during some sysbench tests because the SDRAM has exceeded its temperature limit
Recently Sebastien Jan at TI found that on tilt-3.3, cpu_idle is interacting badly with smartreflex and the wrong Vcore can be selected for 4460.
At the moment we disabled 1.2GHz on tilt-3.3, we think we have a fix + workaround and I'll update with it tomorrow.
tilt-3.3 is updated with the fixes and workaround of disabling CPU_IDLE, please give that a try.
Andy,
Disabling cpuidle is a bit of extreme workaround if one works on power management. :)
Can you point to any discussions about the problem?
