Subject: Re: [Bugme-new] [Bug 10473] New: Infinite loop "b44: eth0: powering down PHY"

Hi!

Maybe this can help:
Using a new .config, I started to enable/disable options and test.
What I found is that if I enable "3G/1G user/kernel split", the kernel
works (it boots normally, the network interface works, etc). If I
select "3G/1G user/kernel split (for full 1G low memory)" I get the
infinite loop of "b44: eth0: powering down PHY".

Working config file (on 2.6.25) is attached.
Diff to the non-working is below:

Can this be the cause?

Thank you!
