Oh, sure thing. The dmesg always prints 'tsc:' - I somehow sticked to it... >> -#define MAX_RETRIES 5 >> -#define SMI_TRESHOLD 50000 >> +#define MAX_RETRIES 5 >> +#define TSC_THRESHOLD (tsc_khz >> 5) > > This breaks pit_hpet_ptimer_calibrate_cpu() because at that point tsc_hkz is > 0. That did not show up with my testing, sorry. I guess pit_calibrate_tsc() never failed for me. Hmm, actually it looks like quick_pit_calibrate() does the job for me so pit_hpet_ptimer_calibrate_cpu() is likely not even called. Would this: #define TSC_THRESHOLD (tsc_khz? tsc_khz >> 5: 0x20000) work for you instead? Or alternatively at some point when chasing this down I used: #define TSC_THRESHOLD (0x10000 + (tsc_khz >> 6)) The first one seems better though. I can send v2 next week if you like it. --nX > Thanks, > > tglx
