We have Debian users who happily used 2.4.27 on their Cobalt Raq1 and Qube 2700. However, since we moved to 2.6 these machines stopped working. I found out that the network driver (tulip) is no longer working on these machines. Today I tried to track down when this started to happen but I couldn't find a 2.6 release where it actually worked. The 2.4.27 release we have is based on Peter Horton's patches from http://www.colonel-panic.org/cobalt-mips/ Today I tested current git, and 2.6.18 (which work out of the box), as well as 2.6.12-rc2 and 2.6.16-rc1 with Peter's patches. In all of these releases, network would work fine on a RaQ2, but not on a RaQ1. I'm not sure what information to report because I found nothing obvious. In 2.4.27, we get: PCI: Enabling device 00:07.0 (0045 -> 0047) tulip0: Old format EEPROM on 'Cobalt Microserver' board. Using substitute media control info. tulip0: EEPROM default media type Autosense. tulip0: Index #0 - Media MII (#11) described by a 21142 MII PHY (3) block. tulip0: MII transceiver #1 config 1000 status 7809 advertising 01e1. eth0: Digital DS21143 Tulip rev 65 at 0x100000, 00:10:E0:00:27:5C, IRQ 4. wheras 2.6.16-rc1 has: PCI: Enabling device 0000:00:07.0 (0041 -> 0043) tulip0: Old format EEPROM on 'Cobalt Microserver' board.

The address is different but I doubt this makes a difference because the RaQ2 shows the same difference and here networking works. I also noticed the following in the boot logs of the RaQ1 with 2.6 that doesn't happen with 2.4, but that's because 2.4 doesn't have such a warning: Galileo: revision 2 Galileo: PCI retry count exceeded (06.0) Does anyone who knows about Cobalt hardware have any idea where to look? I'm happy to send boot logs and test patches if someone wants to investigate this problem. -- Martin Michlmayr http://www.cyrius.com/
