gdb+qemu+rtems: Problem #2 in offset computation

Hi,

I'm trying to debug RTEMS running in QEMU (x86) with gdb. The program 
hangs on

./rtems-4.8.1/c/src/lib/libbsp/i386/pc386/timer/timer.c:476

which is

printk("Problem #2 in offset computation in Calibrate_loop_1ms in file 
libbsp/i386/pc386/timer/timer.c\n");

I found just one related message, 
http://article.gmane.org/gmane.comp.emulators.qemu/17806, where the 
author advises to recompile the (Linux) kernel of the host system.

Is this a known issue ? And if so, is it an RTEMS bug or QEMU bug or 
anything else bug ? And, is there a known workaround that would make 
RTEMS boot ?


Thanks !

Tomas

P.S.

I have RTEMS 4.8.1, QEMU 0.9.1, host OS is FC9 with  2.6.25-14.fc9.i686 
kernel.
