Re: Kernel Installation Issues
Jim Worthington scripsit:
|1)Boot Message - I get the following message when booting:
|
|
|Oct 8 17:10:10 hercules syslogd 1.3-0#6: restart.
|Oct 8 17:10:11 hercules kernel: Cannot find map file.
|
|What is a map file?
Map of kernel symbols (= functions and external variables)
|Where is it supposed to be?
/usr/src/linux/System.map
/boot/System.map
/System.map
(any of the three, if more than one they'd better be the same...)
|How do I get rid of the message?
Under debian you should already have /System.map, a symlink to
/boot/System.map-2.0.x (x = kernel minor, whatever that is in your
case).
|2) Where is the /boot/psdatabase file used?
ps w
which shows the "channels", i.e. the kernel function the code is in.
|I manually installed a new kernel (no debian package) and need to know
|if it was done correctly. After compiling the 2.0.13 pnp patched
|kernel, I did the following:
|
|a) cp /usr/src/linux/arch/i386/boot/zimage /boot/vmlinuz-2.0.13-pnp
|
|b) cp /usr/src/linux/System.map /boot/System.map-2.0.13-pnp
|
|c) I then re-linked /vmlinuz and /System.map to point to the newly added
|files in /boot. I then ran lilo and rebooted.
|
|It's working, but there are some loose ends that I am concerned about.
|I've had the "cannot find map file" message since day 1, so it's not
|related to installing the new kernel.
See the links above, you need the /System.map to be correctly linked
too.
|The /boot/psdatabase file is linked to /boot/psdatabase-2.0.0. I
|couldn't find any corresponding files in the newly compiled kernel
|directory structure. It would seem that I should have a
|psdatabase-2.0.13-pnp as well.
Just do
rm /boot/psdatabase
psupdate
ln -s /boot/psdatabase-2.0.13-pnp /boot/psdatabase
Ciao,
Arrigo
