[opensuse-kernel] driver load question
Hi, I've asked this question on the opensuse list but was met with silence. I have had an intermittent network connection problem since new with my msi 945GCM7 ICH7 motherboard with RTL8111C giglan. This problem has spanned factory alpha to present 11.0 retail with 2.6.25.9-0.2 kernel. After boot although everything reports as working, my network won't connect. Sometimes restarting the network will make it work but most times not. If it is not working ethtool reports a speed of 1000Mb/s, if it is working a speed of 100Mb/s (router speed) is reported. I found in the beginning, starting with the NIC off in the bios and then rebooting with it on made it work but not always. I have changed cables etc. I compiled the r8169 driver into the kernel and this has solved the problem 99.9% but I have to recompile after every kernel update and still have to reboot when 0.1% of the time. The problem occured yesterday so I decided to check good and bad boot logs and found the revision number was 0xFF when the nic doesn't work and 0x02 when it does. The relevant lines from log:- done eth0 device: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev ff) eth0 IP address: 10.0.0.54/24 doneSetting up service network . . . . . . . . . . . . . . . .done done eth0 device: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) eth0 IP address: 10.0.0.54/24 doneSetting up service network . . . . . . . . . . . . . . . .done What can I check for next? I enabled KDB on last compile but I have no experience using it, how would I setup a breakpoint when the incorrect version number is loaded?

Dunno if this is relevant here, but maybe you can give this a try. When I had several problems with Intel NICs, disabling the MSI interrupts at the kernel boot prompt made them go away; this was on an older 2.6.16 kernel, though. Please try adding "nomsi" (without the "'s, of course) at your GRUB prompt and see if it helps.

l8er manfred Thanks manfred, I will try that next kernel upgrade as the problem is rare with the driver compiled in. I would love to know what is actually going wrong and causing the version number to change. regards Dave P.
