I have found a single config change that causes the problem. With:
# CONFIG_HIGH_RES_TIMERS is not set
kqemu works correctly, whereas with:
CONFIG_HIGH_RES_TIMERS=y
the problem appears. Any idea why that causes a problem? Is it a bug?
Anyway, at least for now I have a solution. Thanks for your help.
Steve.
