So…  I installed Wheezy on the G5 and immediately did a dist-upgrade to Jessie.  This time it boots without incident.

With Jessie installed this way, it doesn’t go into “leaf-blower” mode.

In case it helps, here’s a sample from the output of “lsmod” —

root@bigal:~# lsmod | grep i2c
i2c_algo_bit            7980  1 nouveau

root@bigal:~# lsmod | grep wind
windfarm_cpufreq_clamp     2781  1 
windfarm_smu_sensors     6735  1 
windfarm_smu_controls     7094  7

windfarm_lm75_sensor     3989  1 
windfarm_smu_sat        7056  5 windfarm_pm112

Does this help?

PS:  If you’re interested in chasing down the “IPv4 dhcp doesn’t work” problem, I can provide logs from both the G5 dhcp client and the dhcp server (using dnsmasq).
