A sample panic is at the end of this email. I have updated to 7.0-RELEASE-p2 using the GENERIC amd64 kernel and it is still the same. The system is a Gigabyte GA-M56S-S3 motherboard with 4GB of RAM, an Athlon X2 6400+ and 3 x Maxtor SATA 750GB HDD's (only the first is currently in use). The first disk is all allocated to FreeBSD using UFS. There is also a Linksys 802.11a/b/g card installed. I have flashed the BIOS to the latest revision (F4e). The onboard RAID is disabled. At the moment there is no exotic software installed. Although I have been using FreeBSD for a number of years this is the first time I have experienced regular panics and am at a complete loss trying to work out what is wrong. I would be grateful for any advice anyone is willing to give to help me troubleshoot this issue.
