I'm the one who started the kernel thread mentioned above. I run Aurora not Debian on my Ultra5 so I can't really test your Debian packages. However, I have been using a private forward-port of a patch to revert the problematic SPARC kernel change in the 2.6.26 and 2.6.27 kernels, and at least for me reverting the change fixes the X server but hasn't caused any ill effects. /Mikael -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
