    Subjectx86 - Boot hangs at Calibrating delay loop on AMD SC520
    I now have U-Boot booting 2.6.33 (abandoned 32-bit Boot Protocol and got a
    pseudo BIOS working)

    During boot I was getting a warning at arch/x86/kernel/rtc.c:125 and the
    kernel hung at Calibrating delay loop... Also, all boot messages have a
    zero time-stamp.

    I have tried a kernel and get the same freeze calibrating the
    delay loop.

    I have tried with and without the AMD Elan Extended (non-PC) x86 platform

    I first assumed that the RTC is not working - I wasn't initially doing
    anything relating to the SC520 RTC in U-Boot. I have added initialisation
    code (as per the ÉlanTMSC520 Microcontroller User’s Manual Order #22004B)
    and confirmed that the RTC is working in the SC520.

    If traced back how the delay loop is performed and that has led me to
    arch/x86/lib/delay.c where I promptly got very lost.

    Any ideas?
