Hi all!
I compiled l4linux and trying to start it in qemu under Linux (Mandriva 2008.0). But when starting, linux is trapped
my menu.lst is like this: [------------------------------cut------------------------------] title L4Linux 2.6 [console] kernel $(A)/bootstrap -serial modaddr 0x03000000 module $(B)/fiasco $(FIASCOARGS) module $(B)/sigma0 module $(B)/roottask -symbols -lines task sigma0 boot_priority 0xA0 task roottask boot_priority 0xA0 task modname "names" boot_priority 0xA0 task modname "log" boot_priority 0xA1 task modname "dm_phys" boot_priority 0xA0 task modname "simple_ts" boot_priority 0xA0 task modname "l4io" boot_priority 0xA3 task modname "loader" boot_priority 0xA0 allow_cli task modname "bmodfs" attached 7 modules module $(B)/fiasco_symbols module $(B)/fiasco_lines module $(B)/names module $(B)/log --prio 0xA1 --buffer 0 module $(B)/dm_phys module $(B)/simple_ts -t 380 module $(B)/rtc module $(B)/l4io module $(B)/bmodfs module $(B)/libloader.s.so module $(B)/libld-l4.s.so module $(B)/run module $(B)/con_demo2 module $(B)/vmlinuz26 module $(D)/cfg/l4linux26.cfg module $(RD_DENV) module $(B)/l4con module $(B)/loader --fprov=BMODFS con_demo2 run l4linux26.cfg vbeset $(VBE_MODE) [------------------------------cut------------------------------]

So, the trap occurs when returning from an interrupt handler. And also the address 0xf0035e9b is seems to be somewhere in L4 kernel, not in linux itself.
What it can be and how can I resolve this? Thanks in advance, Valery.
