Public bug reported: Hi, we use to boot our machines the diskless method through pxe + initramfs + squashfs +unionfs, and it worked great with kernel 2.6.20-16, but we need to migrate to kernel 2.6.24 and something strange is happening.
We use motherboard intel dg35ec which has a "Ethernet controller: Intel Corporation 82566DC Gigabit Network Connection" (e1000 module). When it boot for first time, can't open /tmp/net-eth0.conf kernel panic That mean that the kernel couldn't bring up the eth0 interface, but a few lines before that appear: ipconfig:segfault at 400bf4 rip 400bf4 rsp "ex_number" error 14 So, I managed to put "strace" into the initramfs and add to the pxelinux.conf "break=mount" in order to get a shell in the initram and debug the problem. the module e1000 is load successfully and without problem $>modprobe e1000 Intel(R) PRO/1000 Network Driver - version 7.3.20-k2-NAPI Copyright (c) 1999-2007 Intel Corporation.
