: if the system crashes, coredumps and then want's to reboot it displays
: "automatic reboot in 15 seconds, pree any key to stop" - but it won't react
: to a keypress - the same worked fine with syscons

setting PCVT_KBD_FIFO to 0 resolved the problem for me - thus i think the bad

any idea ?)

p.s.: a good way to crash the system (for testing purposes :-) is
modload -e union_init /lkm/union_mod.o
