Hi,
In order to increase the Fiasco performance, I removed all debug-stuff from the kernel. But as soon as I remove the JDB, I receive a kernel trap on all starting apps:
2.00 IP=00103480 Trap=03 [Ret/Esc] 4.00 IP=00112bc0 Trap=03 [Ret/Esc]
Do you know what might cause these traps?
Attached is my fiasco.config and below some more output...
