More and more mainboards can have FLOSS firmware, but there is also buggy firmware in disks and other devices. Warren helpfully pointed us to > http://sourceforge.net/projects/fuse-ufs2/ Thanks, Warren! Sourceforge was kaput when I tried to check it out. I'm hoping that it is a high quality implementation, and, being fuse, will solve the kernel panic problem. I plan to look at the filesystem regression tests and see if I can think up any additional test cases. Chris H typed: > For the record, SourceForge hasn't been available for quite > some time. Slashdot reports: The short version is that a storage fault led to significant filesystem corruption, and we had to restore a massive amount of data from backups. There's a post at the SourceForge blog going into a bit more detail, and describing the steps our Siteops team took (and is still taking) to restore service. http://sourceforge.net/blog/sourceforge-infrastructure-and-service-restoration/ Last time I looked, some (not all) parts of fuse-ufs2 had recovered. > I thought this (fuse-ufs2) might be a nice addition to the ports > tree, and was hoping to put it there. Sounds good.
