SuSE 9.0: kernel modules not found after upgrade from k_athlon-2.4.21-286 to k_athlon-2.4.21-291

Hi all. On a SuSE 9.0 system, kernel modules are not found after a kernel upgrade from k_athlon-2.4.21-286 to k_athlon-2.4.21-291. /var/log/messages shows that the wrong modules.dep is searched for: Jun 10 08:50:45 localhost modprobe: modprobe: Can't open dependencies file /lib/modules/2.4.21-286-athlon/modules.dep (No such file or direc tory) Fortunately, switching back to k_athlon-2.4.21-286 was easy. Has anybody encountered the same problem? Or is it just me? Greetings Sven
