Hy,
comman-dpower dosn't work after the lockup. One time i was able to switch to xmon short before the lockup, so xmon basicly works. Without CONFIG_CPU_FREQ the effects are the same. Vanilla 2.6.9 boots without problems. With the sleep patch the kernel hangs on about 3 of 4 boots...If you compile CONFIG_XMON in the kernel, once it's locked, does command-power work to break into the debugger ? Also, does it lockup if you remove CONFIG_CPUFREQ from the kernel ?
Is there maybe a chance to put some call into the kernel so that xmon gets called short before one suspects the hangup? (and would it be of any use?)
Best Regards, Sascha
