What about the stop after I got the first message using one thread per IRQ with the rmgr way? Is it a known problem or perhaps caused by some misconfiguration on my side?
Do you refer to the 'RMGR denied IRQ 4' issue? RMGR won't give you IRQ 4 as it is already used by the kernel for the debug console. Try the 17 with this setup and it should work.
No, I should have separated the two messages more clearly. I meant this part:
Now the system stops after printing out the message 'l4lx | l4lx_thread_create: Created thread 0e.0b (IRQ17)'.
It's just like this, the system stops at this line and I cannot get into JDB (with the Escape key this time). Qemu itself remains responsive, I can e.g. access its monitor. This only happens when I specify 'l4ser.vkey_irq=17' as argument for L4Linux, otherwise I get only the output of L4Linux on the serial line but the system runs happily.
The attached patch against Fiasco should fix the issue for now.
