I can easily reproduce that with my Sparc Ultra60 here, which is running
as buildd for experimental. The machines has the very same problem. I
will try that tonight.
Best you fetch me on IRC, nick zobel on IRCnet, OFTC and freenode.
If we can get the patch down to something which can also be applied to
a plain Etch kernel, i would also speak with Dann if he as Etch Kernel
Maintainer would be willing to accept the patch for the next point
release kernel. I (as stable release manager) would be willing to accept
it, if Dann is supporting this.
