[Asterisk-Users] ztdummy inaccuracy on linux-2.6

[Tamas]

Hello Steven!

Thanks for answers and suggestions!
I will check the bios again tomorrow. I found some interesting things in
/var/log/dmesg:
...
CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
CPU: L2 Cache: 512K (64 bytes/line)

CPU: AMD Athlon(tm) 64 Processor 3000+ stepping 02

works.
Using local APIC timer interrupts.
Detected 12.557 MHz APIC timer.
testing NMI watchdog ... OK.

Maybe this says somehting...
