After the latest update of rng-tools the CPU usage of the rngd deamon is at 100% on Odroid C1:
$this->bbcode_second_pass_code('', '
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
7467 root 20 0 81196 1700 1248 S 323.8 0.2 1:10.93 rngd
')
Packet versions:
rng-tools 6.10-3
jitterentropy 3.0.0-2
linux-odroid-c1 3.10.107-4
As I understood from the changelog in rng-tools 6.10-3 the linking was fixt with jitterentropy 3.0.0-2.
The workaround curently is to downgrade rng-tools or disable jitterentropy.
