LAN chipset disabled but gets very hot

Fri Aug 03, 2012 2:00 pm

Hi,
I don't use LAN interface and intentionally disabled smsc95xx module in kernel.
However, when I touch it, it's temperature is the same as BCM chipset.
Is that normal situation ?
Does it mean that I didn't fully disable LAN ?

btw,
I conect to my RPi remotely and use only wifi stick (Asus USB-N10), that works excellent.
usb and broadcom issues will never be solved...Too much time passed, too much to be done...

Its normal for it to get hot. Disabling software support for it doesnt stop it getting power, obviously.

The LAN chip is also the USB chip so, even if you turn off the LAN part you still have the USB part, which I'm pretty sure you need :P

Thank you both for reply.
I will now enable LAN to see if the issue with "RPi freeze" is still valid with newest kernel.
Previously (2 weeks ago, source from git) I had contant kernel panics, but I've just updated my kernel and modules with newest sources and see the results.
Don't you all think that RPi has poor SW support...?
Personally, I think more effort (workhours) should be spent for development and code improvement, because soon we'll realize that we have an excellent engine for which a specific gas is no more sold.
