guys any ideas? freebsd 6.2 doesn't play nicely with RealTek 8139 on Toshiba Satellite A100.it hangs with "rl0: watchdog timeout" error.
ifconfig - good, ping - dead.
6.1 works well. What it might be?
Ok. about 6.1. /Standard/All install configuration - works fine, but /Standard/Minimal and all the rest 6.2 etc give me rl0: watchdog timeout. who knows or heard about this? i'm completely puzzled.

Is this card integrated with the motherboard... yeah most likely...

I think I've had this exact same problem with the cheap integrated cards before and them just puking all the time under use. I think our solution (I was building a machine for someone) was to get a better card. That was a tower though. Now, since this is a laptop that is probably not an option.

I'd make sure it's not the cable and see if changing the amount of shared video memory in the BIOS helps (I seem to recall it did). Also... play around with plug-and-play options in the BIOS and see if turning off acpi in the kernel helps. If nothing seems to be working... get a bug report to the project and see if someone can help. I am sure they will do their best (that bug report would have a complete dmesg and all the information the kernel and system knows about your card).

With that problem the bsd internal use IRQ 10 to interrupted hardware(POLLING) so the solution could be in 2 ways.

1. Buy new ethernet card. (Not recommend)
2. Change the PCI or slot that your ethernet card is attacthed to to another slot and then reboot the system. The problem could disappear.

If it's work please tell me too, OK.

Thx guys. But how can I change pci slot for the ethernet card in laptop? btw, the same trouble with the wireless. i use Atheros card, so I decided to roll back to gentoo for a little while before the bug is fixed.

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
hint.apic.0.disabled="1"
hint.acpi.0.disabled="1"

#vi /etc/rc.conf
# eth0 interface disabled
#ifconfig_eth0="DHCP"
# ath0 interface enabled
ifconfig_ath0="DHCP"
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)
