[ 372.564358] [c01b6400] ext3_dirty_inode+0x30/0x90 [ 372.564364] [c016b4b9] cp_new_stat64+0xf9/0x110 You might want to check /home sometime - this looks like an ext3 botch rather than a reiserfs botch, unless reiser4 is stomping on something behind ext3's back. Well, I thought so at first, but: /home is reiser4 / is ext3 no other ext3s ~/doc/literatur is on /home (checked via 'df .'). So, well, although it looks like it ext3 is the culprit, it is improbable that it actually was the one triggering first (I never saw that backtrace before, too). Naturally once Edwards says he doesn't need the partition for analyzing, I'll nuke it and try to reproduce it again :) cheers, Danny
Re: Which version will be merged into mainline kernel?
Hello again, Thanks a lot for all the help, well ... I now use reiser4 as root-partition :-) Everything works ok and I haven't seen any crashes or compatibility problems, simply wonderful :-). If something bad happens I'll let you know ;) However performance is so-and-so, the system was faster with ext3, although I compiled the kernel with -O3 -march=pentium4 -mtune=pentium4 -mno-sse -mno-sse3. Booting the system into KDE takes about twice the time, although I have to admit I was using another harddrive - I now use a 60GB/4200RPM instead an 40GB/4200RPM which both show quite the same hdparm-results, I use the lzo1 plugin (default ccreg40). Are there some settings (or ext3 optimizations) in FC6, or could it be that some of my kernel-settings slow things down for FC6 (the same compiled kernel-binary was already used for ext3). The reiser4-partition is mounted with noatime. These are some features I could imagine causing problems: * Inotify * Adaptive file readahead + hit feedback + fine grained readahead aging * Timer with 1kHz * Readahead-script of the distribution Thanks a lot, lg Clemens
