From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Description of problem: Some of the scsi drivers in this kernel package cannot be loaded. After upgrading from update 2 to update 3 of kernel-smp package, boot fails in a kernel panic when driver for the scsi controller fails to load. So far this problem has been observed for 2 different scsi drivers, aic7xxx and mpt. Version-Release number of selected component (if applicable): kernel-smp-2.4.21-20.EL How reproducible: Always Steps to Reproduce: 1.upgrade to latest kernel-smp rpm 2.reboot Actual Results: System fails to boot -- panics after the attempt to load scsi driver from ramdisk fails with unresolved symbol errors Expected Results: System should still boot normally after kernel upgrade Additional info: The addon modules directory included earlier versions of the mpt driver for the fusion controller, and these versions are able to be loaded (I manually included those modules in a ramdisk and got the system to boot). Whatever went wrong in the build only affected the drivers in the main scsi driver tree.
Here are the unresolved symbols for the aic7xx driver (have not been able to reboot server with LSI controller yet) unresolved symbol _diskdump_mod_timer_Rsmp_149821d8 unresolved symbol _diskdump_del_timer_Rsmp_6e4ae275 unresolved symbol _diskdump_tasklet_schedule_Rsmp_acd0d2f4 unresolved symbol _diskdump_add_timer_Rsmp_23163dfb
*** Bug 133847 has been marked as a duplicate of this bug. ***
The unresolved symbols belong to diskdumplib.o (added in U3 to support disk-based dump). The aic7xxx and mpt fusion drivers in U3 depend on diskdumplib.o. This should have been picked up during the install, and diskdumplib.o should be in the initrd. Is diskdumplib listed in /etc/modules.conf? What procedure did you use to update the system? Were there any errors?

It was an update problem -- kernel was upgraded without upgrading mkinitrd first. Problem resolved, thanks.
