I run this shell script after each upgrade and 'make delete-old-libs' to check if any shared objects need to be rebuilt: #!/bin/sh for file in `find /bin /sbin /usr/bin /usr/sbin /usr/lib /usr/libexec /usr/local -name "*"` do echo $file ldd $file >> /root/ldd_results 2> /dev/zero done After the upgrade to r205248, the script freezes at seemingly random points. I can still ssh to the machine (using keys), i.e. I see the welcome message, but cannot get to the console prompt. On the serial console I cannot get the prompt after entering the root password. I have top(1) running interactively in another window. The sh process is in "getblk" state, and ignores kill -9. But there's no ldd process. And shutdown requests are also ignored: # shutdown -r now Shutdown NOW! shutdown: [pid 8019] # and nothing happens after that So I have to do a cold reset via MP. On ia64 r204322, this script causes no problems.
