ULE has been revamped heavily on 7.0 and the > version on 6.x is old, and is known to contain some bugs. Is it particular to 6.x *SMP* systems ? I've been using 6.3-R with ULE for about a fortnight without any trouble (on a pentium4-m UP). I was drivent to switch to ULE because I suffered awful slow-downs, mouse jerkiness and all: when compiling kernel or a port, for instance, mouse would not respond with fluidity in firefox, switching tabs would take many seconds, and watching TV with vlc showed many cut-offs and fixed pictures (not related to network traffic or bandwidth limitations). The transition to ULE made them disappear (still occasional mouse jerkiness though). I suppose the enhancements/corrections of 7.x ULE won't be MFC'd ? gregory delfly
