when I do a soft reboot on beta7 the board lookup and dosen’s bootup again. I have to power cycle it. it is an old 511 board.

you have tried only this one or some other board also?
only this one at the moment. The firmware has been upgraded to 2.8.
on 133c works ok.
Everyhting i do seems to push it to 100% cpu utilizzation but it seems to work fine.
Each character i type on new trerminal box push the cpu to 100%, but then come back to zero…
Hope it is going to be workable on the field.

this is due to color console 
it takes some resources, but only when you are logged in, and it is more easier to work in console if these color markings are used (at least for me), so i think, that it is ok
hope you will be able to fix the reboot issue on the old 511 because i have a bunch of them.

Have same issue here on my test board but unlike yours, this one does not run correctly, extremely difficult to get logged into Winbox or via serial.
If I downgrade the issue clears up.

If you are using 2.6.20 kernel, and sch_htb or mirred(iproute2 action) - check please netdev maillist, i report few critical bugs in them and they are fixed in git tree. They can cause kernel panic.
