Automatic update erases line in sysctl.conf and emits "Watchdog timeout" msgs

[salvor]

This problem might be specific to vmware.  I'm running pfSense inside VMware Player 3.1.3 on Windows 7 x64.

I used automatic update from BETA5-amd64 (Feb 5 snapshot) to RC1-amd64 (March 6 snapshot).
The update erased this line in /etc/sysctl.conf:

kern.timecounter.hardware=i8254

And after updating, I started getting "em0:  Watchdog timeout – resetting" messages on the console after upgrading. 
I got about 20 of these messages within 30 minutes of upgrading.  My em0 is LAN.

Manually adding the i8254 entry back to /etc/sysctl.conf and rebooting didn't get rid of the "Watchdog timeout" messages.  About 16 showed up within a couple minutes of rebooting.

Seeing the endless watchdog timeouts as well, and ntpd service refuses to start.  Reverted back to March 1st RC1, started somewhere between the 1st and the 4th of March snapshots.

I too have watchdog timeout messages on ESXi 4.1 and Workstation 7.1.3 setups, em adapters, both on 2.0RC1 i386 built on Fri Mar 4 10:27:33 EST 2011

Last known good snap was March 2nd.

March 3rd has some error loading rules issue that was fixed on the 4th, and its from the 4th on that these issues popped up, wondering if its all relevant.  Jimp fixed the loading rules error so maybe he has an idea of what could possibly be wrong

Error was confirmed for me too. With March 6 snap i386 full install I would get the same error except on em1, which is my LAN interface.

Check the bug tracker. The watchdog timeouts are from the new yandex em driver. We may end up reverting them, as they are causing this and other issues.
