Well, you ALWAYS have to rebuild all LKMs, if any kernel data structures change! LKMs are Loadable Kernel Mdoules, i.e. parts of the kernel that can later be loaded into a running system to extend its functionality. I.e. if you don't have NFS compiled into your kernel, then NFS mounting some remote file system will first load the NFS LKM (and crash your system, if the two don't match!). } > - Can you boot single user (enter "-s" at the "Boot: " } > prompt, fsck the file systems and mount (r/o) your } > /var partition ? } } Yep, this works fine. There is a problem however when I started up: } starting local daemons: } /usr/sbin/ncrcontrol: no symbol "_ncrp" in "/kernel" } } Any ideas? Yes, and I thought I fixed this a few days ago. I remember typing the commit message ... Somebody made many driver symbols "static" (and this was a very good thing!), but seems to have missed the fact, that "nncr" is required for communication between ncrcontrol and the NCR driver (well, and that was not obvious :) Well, I just checked the CVS log, and I remember, that the commit was interrupted due to a loss of the TELNET connection. I'll try the commit later today, again. Now the line quality is just too bad (tens of seconds delay ... ) regards, STefan -- Stefan Esser, Zentrum fuer Paralleles Rechnen Tel: +49 221 4706021 Universitaet zu Koeln, Weyertal 80, 50931 Koeln FAX: +49 221 4705160 ============================================================================== http://www.zpr.uni-koeln.de/~se <se@ZPR.Uni-Koeln.DE>
