[...] Worrisome. Can you get a backtrace from this segfault? udev maintainers, any advice on how to do so? Aside from that: Please attach full "dmesg" output from trying 2.6.32-45 from squeeze and a 3.x.y kernel from sid, experimental, or squeeze-backports. The only packages that should be needed from outside squeeze for this test are the kernel image itself, linux-base, and initramfs-tools. If the bug is still reproducible with a 3.x kernel, we can get help from upstream. If not, we can try to find what change fixed it and apply the same fix to squeeze.
