Hm. This resembles me something. Can you reproduce the same problem if you apply patches from ftp://ftp.namesys.com/pub/reiserfs-for-2.4/testing/quota-2.4.20/ These patches add quota support to reiserfs, but also change some new inode-related operation to prevent deadlocks like you are seeing. > Any I/O freezes and even after killing the script, the remaining cp and > mv commands don't terminate. They are in status "D". A simle "ls > /backup" never comes back. Only a hard powerdown fixes this situation, > because "init 6" etc. doesn't work. I have even activated the reiserfs > debug, but I don't see any additional info. Try executing sysrq-t after the lockup happens, then send us decoded output plese. Thank you. Bye, Oleg
