Hi all,
I have some trouble while creating an installation with the kernel
2.4.33 + RTAI patches 3.4
The kernel is woking good but I cannot load any module.
The error reported by modutils is some unresolved symbols, printk and
kalloc for example. the CONFIG_MODVERSIONS option is not an issue - the
problem is present with and without that option - remark that I always
rebuild the entire kernel tree and modules so there is not any mismatch
between the modversions.
I noticed that
- sometimes the kernel i built with the modversions
incerrectly, that means that /proc/ksyms reports for example
printk__ver_prink instead of printk_R_xxxxx . it seems a compilation
error.
- it seems that modutils cannot resolve the symbols, because if depmod
or insmod reports printk not present, I can see that /proc/ksyms haves
printk -- without the modversions, for example.
- ksyms -a reports nothing
Anyone experienced something like this?
Thank you in advance!
Regards
ing. Federico Fuga
