Just cross posting this. Hmmmmmm....I don't seem to be able to post with the attachments. Here is the kernel panic/dump and some other information: The system in question is an ASUS M2N32WS motherboard running an Dual-Core Athlon64. The 2820SA was tested with firmware revisions 9194 and 8832. The running o/s is Fedora Core 6 Test 3 with their latest renditions of 2.6.18. I also compiled and tested vanilla 2.6.18 with the kernel configuration from Fedora's kernels. The driver version of aacraid reports as 1.1-5[2409]-mh2. udevd[541]: add_to_rules: invalid rule '/etc/udev/rules.d/50-udev.rules:153' Unable to handle kernel paging request at ffffc20010084044 RIP:
