On startup some init-skripts access this node and print out a protection fault. i am having this on pcmcia and swap startup. My system is an amd64 @3000+ in an Acer Aspire 1501Lmi at 64bit mode running gentoo. .config is the same as on 2.6.10-rc1 which works good. cat on /proc/devices gives the same problems. The kernel has just a patch for wbsd (builtin mmc-cardreader) from Pierre Ossman in use, everything else is vanilla. Does anyone know of this issue and perhaps on how to solve this?
