I suspect that one of the packages in the last system updated is causing problems with the system rebooting. When I reboot, the server hangs on udev.
Here are a list of the updates that preceeded the problem:
Oct 21 18:04:03 Updated: 6:kdelibs-3.5.4-26.el5_7.1.x86_64 Oct 21 18:04:06 Updated: httpd-2.2.3-53.el5_7.3.x86_64 Oct 21 18:04:07 Updated: postgresql-libs-8.1.23-1.el5_7.2.x86_64 Oct 21 18:04:08 Updated: 1:mod_ssl-2.2.3-53.el5_7.3.x86_64 Oct 21 18:04:10 Updated: 6:kdelibs-devel-3.5.4-26.el5_7.1.x86_64 Oct 21 18:04:11 Updated: 1:autofs-5.0.1-0.rc2.156.el5_7.3.x86_64 Oct 21 18:04:12 Updated: httpd-manual-2.2.3-53.el5_7.3.x86_64 Oct 21 18:04:14 Updated: kernel-headers-2.6.18-274.7.1.el5.x86_64 Oct 21 18:04:15 Updated: 1:php-pear-1.9.4-3.el5.remi.noarch Oct 21 18:04:30 Installed: kernel-xen-2.6.18-274.7.1.el5.x86_64 Oct 21 18:04:39 Installed: kernel-devel-2.6.18-274.7.1.el5.x86_64 Oct 21 18:04:50 Updated: 6:kdelibs-3.5.4-26.el5_7.1.i386 Oct 21 18:04:51 Updated: postgresql-libs-8.1.23-1.el5_7.2.i386 Oct 21 18:04:53 Updated: 6:kdelibs-devel-3.5.4-26.el5_7.1.i386
/var/log/messages shows that the system went down for reboot, but nothing was logged when the machine tried to come back (and hung at udev). It's not saying udev failed, just prints udev and hangs.
Interestingly, when the system was hard-reset it booted without an issue (udev OK). Issued shutdown -r, and the system hung on udev. Again, held the power button to kill the system. Turned it back on after the hard-reset and it came up (udev OK). It's up now after the hard-reset.
System: RHEL release 5.7 (Tikanga) Kernel 2.6.18-274.7.1.el5xen (x86_64) (Dell Poweredge)
Any ideas on which of these packages could cause udev to hang?
