Kronos 2.6.1 become very unstable with the attached test application

[willll]

This test application starts on real HW, but even though it is not doing much it does not behave as badly as kronos 2.6.1 does :

R0 = 00000071 R12 = 00000000
R1 = 00000000 R13 = 00000000
R2 = 01E00000 R14 = 00000000
R3 = FFFFFF80 R15 = FFEBD251
R4 = 060FFBC0 SR = 000000F1
R5 = 0000000F GBR = 060FFC00
R6 = 00000000 VBR = 06000000
R7 = 00000000 MACH = 00000000
R8 = 00000000 MACL = FFDA2100
R9 = 00000000 PR = 000003FF
R10 = 00000000 PC = 00000002
R11 = 00000000
Master SH2 invalid opcode

Kronos needs to be kill with : pkill -9 kronos
