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!

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) ssb: Sonics Silicon Backplane found on PCI device 0000:02:0e.0 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. -- Wojciech M Zabolotny wzab@ise.pw.edu.pl -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
