Hi Dann The backported patch bugfix/ipv6-disallow-RH0-by-default.patch you checked into the etch branch of the kernel causes the kernel to issue the message, "Unable to handle kernel paging request at virtual address 6261746d" (see boot log below) on the Linksys NSLU2 (arm). The system boots successfully with all of the rest of the patches in series 13 applied. I can still ssh to the system, but the system is not stable. For instance, ifconfig never finishes running. Below the boot log, I have included the active process list after running ifconfig.
It looks like the first version of the original patch in 2.6.20 and 2.6.21 was broken [1], The fix for the broken patch in 2.6.21 was committed after 2.6.21 was released [2] and is included in 2.6.21.1. I haven't looked at your backported version enough to see if the problem is the same as the problem described in the original patch.
