Hi Jason, Jason Woofenden <jason@jasonwoof.com> (30/01/2011): > Here is my report on how I got the siliconmotion driver to run: […] many thanks, that looks quite promising. I'll try and look into it in the next days/weeks, feel free to poke me if you see no action on this bug in a while. Néstor, Tzafrir, see Jason's full report at: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=594684#25 (I've added them back in Cc, the BTS doesn't do that automatically.) > 1) I mirrored the sarea patch at: > http://jasonwoof.com/downloads/01_mips-sarea.diff because the link > above seemed dead. I believe it's the same patch though. I'm attaching it to this mail. Having the patches in the BTS is usually a safe way to have them accessible no matter what happens to external websites. KiBi.
