GENERIC kernel works ok >How-To-Repeat: Enable Multi-Core capabilities in BIOS, install FreeBSD 6.2 (default options, SMP kernel) on aac-based raid5, try to boot system. I've got instant panic after aac0 initialisation. >Fix: 1. Disable Multi-Core in BIOS. This also disables HyperThreading. 2. My coleague had similar problem with another Adaptec controller, also aac-based. Panic was not immediate, but regular. He swithced to amd64 kernel, and problem disappeared. >Release-Note: >Audit-Trail: >Unformatted:
