Reboot hangs when R8169 loaded, Intel D945GCLF Atom MB, 2.6.28-6 vanilla kernel on Debian etch if any card is in PCI slot. I do know truly that the r8169 module is the culprit, but since r8169 has fingerprints on the problem (see below), and I have had several issues with the D945GCLF before for me with this driver, I figured might as well start there, and report it as such. If I am filing this in the wrong place, please direct me to a better one. Tested 2.6.28-5 and 2.6.28-6 on the D945GCLF. With no devices in the PCI slot, and r8169 enabled, unit will shutdown -h and showdown -r just fine, and r8169 working in practice. However, when any PCI device, and I tried video capture cards, USB port expander cards, unrelated network cards using different chip sets, WiFi PCI cards, any card I tried, shutdown -h continued to work fine, but any attempt at reboot with either reboot command or shutdown -r resulted in a system that did not reboot, just displayed the message as follows: Will now restart r8169 0000:00:00.0: PME# enable Restarting system machine restart And then it just sits there. I did not have this issue with this Motherboard D945GCLF with 2.6.26. Here is what makes me think the r8169 might be involved: * When I ifdown eth0, reboot still does not work; * When I rmmod r8169 just prior to reboot, then reboot works fine (and there is then no r8169 in the Restart message) ; * When I disable the r8169 in BIOS, the reboot function works fine again (obviously not the Ethernet port then) I include an excerpted lspic -v and dmesg below, for reference. I can live with the rmmod r8169 just prior to reboot as a work-around, but it seems like there must be a cleaner fix somewhere.
