From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031114 Description of problem: After installing kernel-2.4.21-9.EL.i686.rpm and kernel-unsupported-2.4.21-9.EL.i686.rpm from RHES3 Quarterly Update #1 I rebooted my system and noticed that the HiSax ISDN driver could not be found during system startup. Manually running depmod -a and rebooting fixed the problem. So it seems to me that when rc.sysinit runs depmod it ignores the modules from the unsupported subdir. The postinstall script from kernel-unsupported-2.4.21-9.EL runs depmod -ae but without specifying the kernel version. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. update to kernel-(unsupported)-2.4.21-9.EL 2. 3. Additional info:
The problem is that the kernel-unsupported package runs depmod for the worng kernel, i.e. the one that is running while the package is installed. And depmod in /etc/rc.d/rc.sysinit won't do any good since it uses the -A flag and the timestanps for the modules will be as they were in the rpm, i.e. quite old. To remedy this problem, the %post script of the kernel-unsupported (and kernel-smp-usupported) packages should be modified to do depmod for the version being installed.
Thank you for such a clear bug report and analysis. A fix for this problem has just been committed to the RHEL3 U2 patch pool, and it will first be available (internally at Red Hat) in kernel version 2.4.21-11.EL.
