Hi,

I am new to the list, i am experiencing a bizzarre issue with debug kernels. I used debug kernels in the past without issues. The issue is that the last two debug kernels i tried do not boot. So i cannot boot debug kernels.

Kernels that boot normally:

3.7.3-101.fc17.x86_64 3.7.4-104.fc17.x86_64 (and olders)

Kernels that do not boot. 3.7.4-104.fc17.x86_64.debug 3.7.3-101.fc17.x86_64.debug (older kernels untested)

It is perceived as a increasing slowness in dracut but when one press ESC one will find that "Watchdog detected hard LOCKUP on cpu 1! and a call trace, in fact, there are many call traces in which the cpu number changes. Ultimatelly, one needs to press the reset button.

HW: FX-6100 on 990FX chipset

Thanks in advance.
