There seems to be something I would call a bud in ReiserFS at least in kernel 2.6.11.11 which can cause the system/computer to freeze. It is caused by a corruption of the FS but at that point I expected to have some inaccessable files which I already know from FS corruptions but not to hang the system. If someone thinks it's worth investigating, please read further. Yes, I know that working with a corrupt FS is nothing good but my intention was simply to save as much of the files as possible before doing a rebuild-tree just in case it's all gone after that. As I said, my experience with corrupt ReiserFS was good with the knowledge that some files/direcories would be incaccessible. But this time the System was rendered unuseable when accessing certain directories - no more mount/umount or even sync were possible (they simply did not return) so there was no way to shutdown the machine. IMHO this should be considered as a severe bug - refusing to read a corrupt portions of a FS is OK but rendering the system unuseable is bad. I'm wondering what kind of information I can provide so the source of this can be found. Here some but if you want more, please tell me: Kernel 2.6.11.11, Gentoo-Linux, SMP (HyperThreading P4, 3GHz) Here some portions of /var/log/messages which may show what's about: the messages just before the system got unuseable: ************** Aug 5 22:17:22 master ReiserFS: sdc1: warning: vs-5150: search_by_key: invalid format found in block 27594920.
