Failure from my side, as usual. Kernel versions are talked about in those blog posts: http://ikibiki.org/blog/2010/02/28/Where_have_you_been/ http://www.itp.tuwien.ac.at/~mattems/blog/2010/03/03#newer_linux_32_33 You might want to wait until another revision of the .32 or .33 kernels is available, then check whether the issue is still here. If you were to open a bug in Debian, please put the kernel function name or file path in the subject, that's AFAICT another story. Mraw, KiBi.
