I've installed kernel-lt-3.2.57-1.el5.elrepo.i686.rpm on my CentOS 5.5 system because I'm trying to troubleshoot a third party USB hardware issue that causes the system to hang. If I issue the commands:
echo 1 > /proc/sys/kernel/sysrq echo "c" > /proc/sysrq-trigger The system looks like it's starting to capture the dump information, but complains about many kernel-module version mismatches and the kernel that it says it's mismatching is cryptic. For example: Mounting sysfs filesystem Creating /dev Creating inital device notes Loading scsi_mod.ko module insmod: kernel-module version mismatch /lib/modules/3.2.57-1.el5.elrepo/scsi_mod.ko was compiled for kernel version M?**=a while this kernel is version 3.2.57-1.el5.elrepo The M?**=a is the cryptic part. The ** are actually suppose to be boxes, but I don't know how to make that system. With the latest CentOS 5.X debug kernel (kernel-debug-2.6.18-371.6.1.el5) when I issue those commands kdump starts and captures system information in a vmcore file. Does kernel-lt-3.2.57-1.el5.elrepo have the capability to capture kernel dump information? If so, any appearant indications of what I am doing wrong. If no, I will work on compiling my own 3.2.57 kernel with the necessary parameters. Any suggestions are appreciated. Thanks for you help in advance. Regards, Antonio
