This has been reported for ia64 as well. Fixed in our current source tree, will be fixed in the next rawhide kernel. |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; compaq) Description of problem: The installed kernel sources set up modules to expect modversion symbols of the form sym_Rsmp_VER. The smp kernel binary provides symbols of the form sym_RVER (confirmed through /proc/ksyms) How reproducible: Always Steps to Reproduce: 1. Try to build a module against the smp kernel (ex. drm modules from current XFree86 CVS tree 2. Try to insmod the module 3. Find the missing symbols in /proc/ksyms Actual Results: insmod failed expecting sym_Rsmp_VER form of symbols /proc/ksyms showed sym_RVER form of symbols. Expected Results: module should have inserted Additional info: This appears be caused by the linux-2.4.2-vm-1-2-3-gbyte.patch (patch 76 in the 2.4.3-7.src.rpm) which changes ifdef CONFIG_SMP genksyms_smp_prefix := -p smp_ else genksyms_smp_prefix := endif to: ifdef CONFIG_1GB ifdef CONFIG_SMP genksyms_smp_prefix := -p smp_ else genksyms_smp_prefix := endif endif ifdef CONFIG_2GB ifdef CONFIG_SMP genksyms_smp_prefix := -p smp_ else genksyms_smp_prefix := endif endif ifdef CONFIG_3GB ifdef CONFIG_SMP genksyms_smp_prefix := -p smp_ else genksyms_smp_prefix := endif endif leaving genksyms_smp_prefix unset if none of CONFIG_1GB, CONFIG_2GB, CONFIG_3GB is set. None of these will be set on an Alpha.
