I have updated my RT-kernel to version 2.6.33.7-rt29 (the newest RT
version),
and I've found that I've lost Ethernet connectivity.
In the logs I could see messages like this:
Nov 2 09:30:28 wzlaphp kernel: b44: eth0: powering down PHY
Nov 2 09:30:28 wzlaphp kernel: b44: eth0: BUG! Timeout waiting for bit
00000002 of register 42c to clear.
Nov 2 09:30:32 wzlaphp kernel: b44: eth0: BUG! Timeout waiting for bit
80000000 of register 428 to clear.
I was not sure whether the probem is related to the 2.6.33.7 kernel
itself or with the RT patch, so I've compiled also the unpatched version
of 2.6.33.7
It is also not able to communicate with my Ethernet controller, but now
the error messages are different:
b44 0000:02:0e.0: PCI INT A disabled
b44 0000:02:0e.0: BAR 0: set to [mem 0xf4108000-0xf4109fff] (PCI address
[0xf4108000-0xf4109fff]
b44 0000:02:0e.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
ssb: Core 0 found: Fast Ethernet (cc 0x806, rev 0x07, vendor 0x4243)
ssb: Core 1 found: V90 (cc 0x807, rev 0x03, vendor 0x4243)
ssb: Core 2 found: PCI (cc 0x804, rev 0x0A, vendor 0x4243)

b44.c:v2.0
b44: Invalid MAC address found in EEPROM
b44 ssb1:0: Problem fetching invariants of chip, aborting.
b44: probe of ssb1:0 failed with error -22
Now I'm using the old 2.6.33.5-rt23 kernel, and everything works perfectly.

Could you print the Invalid MAC address ?

Known problem.
It's the 2.6.33.7 kernel.
You need to revert this:

Oh,
and if you need the alternate ssb eeprom addess fixes, you need to apply:
