Frebsd 7-STABLE, atapicd, atapicam and Intel errors [SOLVED]

Allright, I`ve played again with an HPET in BIOS little bit.
Results ->
HPET disabled:
kern.timecounter.choice: TSC(-100) ACPI-fast(1000) i8254(0)
dummy(-1000000)
kern.timecounter.hardware: ACPI-fast
HPET enabled:
kern.timecounter.choice: TSC(-100) HPET(900) ACPI-fast(1000) i8254(0)
dummy(-1000000)
kern.timecounter.hardware: ACPI-fast
But now FreeBSD boots also with HPET enabled (really don`t understand
what`s going on).
When I was trying to mount cd with "mount -t cd9660 /dev/cd0 /mnt/cd0",
mount works as expected (atapicd module not loaded).
Then I`ve kldload-ed atapicd, "mouunt -t cd9660 /dev/acd0 /mnt/cd0"
(acd0, not cd0), but this ended with messages like this:
unknown: FAILURE - READ_BIG timeout (retry count 0)
Temporary I`ve disabled HPET in BIOS (Linux got problems too-> he
created gigabytes of log messages in /var/log/messages :D).
Best regards, Jan
