Indeed it must have been as you state but I did not want to do a ROOTFS copy since setting up and cleaning the old LVM settings etc., will cause a lot of compilication. I went ahead and installed a fresh system and then copied the kernel and initrd into the SD card. I however do not remember why I disabled nouveau ... must have been thinking something else...
But yes.. in SSD nouveau was enabled and in SD it was not. That caused a major difference. I am also amazed on how GPU contributes to the CPU task offloading even if graphics is not used (text only mode) On 2/7/15, Burhan Hanoglu <burhano...@gmail.com> wrote: > On Sat, Feb 7, 2015 at 2:37 AM, Bhasker C V <bhas...@unixindia.com> wrote: > >> Thanks all for inputs >> >> SOLVED !!! >> >> >> 1) The fan is fine in my system.
