So I think it's a bestcrypt issue.
what was occurring when the panic occurred?
(In reply to comment #1) > what was occurring when the panic occurred? > I've compiled bestcrypt modules for the 2.6.20-gentoo-r8 kernel, after that I rebooted the system and that panic appeared when system was starting.
On your last good known configuration was it the same version of bestcrypt that you have now? If it is, it might be a kernel regression issue.

Can you please try the latest one from portage? (_p13)
