Re: E450 Fan tray noise

OK I've delved into this a bit deeper...

It looks like there was a patch to the envctrl driver way back in 2.2.16
which changed the way the driver found the environment controls on the sbus.

-			if (!strcmp(edev->prom_name, "SUNW,envctrl"))
+			if (!strcmp(edev->prom_name, "i2c")) {

My Prom returns the names the old way, like this...

ebus0: [auxio] [power] [SUNW,pll] [sc] [se] [su] [su] [ecpp] [fdthree]
[eeprom] [flashprom] [SUNW,envctrl]

So it seems the driver isn't finding the hardware. Prom version problem

PROMLIB: Sun IEEE Boot Prom 3.12.3 1998/12/04 14:20

Is there anyone with an E450 for whom envctrl works?
