It was working for me too on my 951ui at home, but I was having some problems when rebooting the router, so I netinstalled the board - it was no longer visible in the installed packages. No problems since.
My DUDE server x86 on AthlonXP 2000+ 512DDR, Soltek MoBo has gone yesterday
Update to 6.19 kills all the system packages. After install i`ll see kernel panic
some hashes appeared on the monitor connected to station then...
...system stop loading on "Loading with..." Total crash...
Exactly as described.
In the later v6 version Dude was causing major problems, but starting from around 6.15 it was not visible in packages and there was no way to uninstall it. In 6.20 you can see it in package list so you can uninstall it. That is the fix. The ability to uninstall the not working package.
