Well yeah. Your instructions for diagnosing a quirk are to add #define DEBUG to ps3av.c and then send the _output from the kernel log_ ... ? Not to mention that for every quirk reported there's probably 50 users who just figured Linux on PS3 was broken and gave up. > The only 100% (sic) mode is 480p (actual usable resolution is 576x384), which > is quite limited due to the very low resolution.

Sure that's annoying, but not quite as annoying as getting a completely black screen that you can do nothing about - short of hacking the kernel and building your own otheros.bld. cheers -- Michael Ellerman OzLabs, IBM Australia Development Lab wwweb: http://michael.ellerman.id.au phone: +61 2 6212 1183 (tie line 70 21183) We do not inherit the earth from our ancestors, we borrow it from our children. - S.M.A.R.T Person
