This is bug in the handling of per-cpu variables. Andrew Morton and Rusty Russell posted patches to fix it.

Maybe my understanding is a little off, but I thought that I could just rebuild the modules and install them and run depmod and the new module symbols would be in effect. But that didn't work (same error). So then I tried also a make bzImage and make install (which updates the System.map, something that didn't get done with make modules_install). It still would not load (same error). Finally, I rebooted loading the new kernel and that fixed it.

I've seen similar issues when the /boot/System.map file doesn't match the kernel in use (this is particularly an issue for 'depmod' - the standard 'make modules_install' target passes a -F flag to depmod to use the just-created System.map file. -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech msg06852/pgp0.pgp Description: PGP signature

That I get. You're saying that my make install step which updated the System.map in /boot was nullfied because it didn't exactly match the running kernel version. And you're also saying that -F makes it ignore what /proc/ksyms has. But then that leads to the next problem. That System.map doesn't match the /proc/ksyms, so I'm still left with a reboot as my only option. Thinking out loud. But I didn't change the way that the kernel was compiled. Reiser4 is _still_ a module. What am I missing? Blue skies... Todd P.S. Valdis, I think this sig originally came from somebody's NANOG post. :) -- A: No Q: Should I quote at the end of the message?

reiserfs df and du (not the reply in the faq)
first of all, hi, it is my first message from faq -- du says ReiserFS makes space efficiency worse. Use df not du, or use "raw" option for du if your du supports that. st_blocks summed up is less accurate than st_size for ReiserFS because we pack tails, and st_blocks rounds numbers up. -- this means that du, with st_size, must give an higher value than df no? anyway, i had updated reiserfsprogs to version 3.6.4, findutils to 4.1, and i have this output df -h FilesystemSize Used Avail Use% Mounted on /dev/ide/host0/bus0/target0/lun0/part1 478M 366M 113M 77% / /dev/ide/host0/bus0/target0/lun0/part6 14G 1.8G 12G 13% /usr /dev/ide/host0/bus0/target0/lun0/part7 4.5G 80M 4.4G 2% /home --- (on /) du -hsx 102M. --- (always on /) du -hsx * 632kSystem.map 4.5Mbin 4.7Mboot 512 cdrom 32k chroot 4.5kcoda 0 dev 2.5Metc 54M home 4.5kinstall 28M lib 1.5kmnt du: `proc/11129/fd/3': No such file or directory 0 proc 39M root 3.7Msbin 0 spider 32k tmp 1.9Gusr 20M var 285kvice 512 vicepa --- i have also in proc kcore that is 202M, but i thnk that it is stored on ram so, i have 260M of space that is null. i also need to keep the server up, so i can't reboot with a read only fs and make reiserfsck on the partition any suggestion? bye Daniele
