OK i now there is only an pullrequest for this router and this router differ by other lantiq xrx200 devices.
But possible that someone have the same problem.
OpenWrt SNAPSHOT, r9945+40-bc85640cdc with the pullrequest for the Easybox 904xDSL
And have reboots when i try to configure SQM via luci and tc shutdown my router for this reason i try strace:
