I have Digital AlphaPC 164SX 533 MHz, 531MHz
root@aleph:~#uname -a
FreeBSD aleph.km.ua 4.8-STABLE FreeBSD 4.8-STABLE #7: Sun Apr 20 02:49:52 EEST 2003 root@aleph.km.ua:/var/opt/src/sys/compile/ALEPH alpha

it's 4 boot of kernel
1 and 3 - original code (system clock is wrong)
2 and 4 - patched kernel by me:

calibrate_clocks is broken?
P.S. sorry for my bad english.
