OK. we r in business again!!@! I managed to fix the trouble, luckily there are some bright people out there! READ this Toshiba Satellite FreeBSD
. My case was identical, with similar "ACPI, rl0: watchdog timeout, no wireless" problems.
It appeared that wireless card and NIC disagree on the IRQ ground, so disabling NIC made the trick.
All i did:
# vi /boot/device.hints
# eth0 interface disabled
# ath0 interface enabled
ifconfig_ath0="ssid your_ssid_here DHCP"
That fixed all the problems. (as my lappy uses Atheros WiFi card, it was precompiled into FreeBSD 6.2 default kernel)
