Hi, I'm sending this because the kernel message said I should :) [1.] PCI: Bus #03 (-#06) is hidden behind transparent bridge #01 (-#03) [2.] I recently compiled 2.6.18.3 for my laptop, and when I inspected the logs I found this: Nov 27 14:46:41 m03r21a2905 kernel: PCI: Bus #03 (-#06) is hidden behind transparent bridge #01 (-#03) (try 'pci=assign-busses') Nov 27 14:46:41 m03r21a2905 kernel: Please report the result to linux-kernel to fix this permanently OK, so I added append="pci=assign-busses" in lilo.conf and now I see: Nov 27 14:59:09 m03r21a2905 kernel: PCI: Ignore bogus resource 6 [0:0] of 0000:00:02.0 [3.] Keywords (i.e., modules, networking, kernel): PCI Bus [4.] linux-2.6.18.3 11% cat /proc/version Linux version 2.6.18.3 (perbo@cosmos) (gcc version 3.4.6) #1 SMP Mon Nov 20 01:29:03 GMT 2006 [5.] Most recent kernel version which did not have the bug: N/A [6.] Output of Oops.. message: N/A [7.] A small shell script or example program: N/A [8.] Environment [8.1.] Output from scripts/ver_linux: linux-2.6.18.3 4% sh scripts/ver_linux If some fields are empty or look unusual you may have an old version.
