Description of problem: RT kernel fails to boot on blade1 of HSV bladecenter (blade2 boots the kernel and runs fine). Same blade boots and runs RHEL5.2 kernel. Version-Release number of selected component (if applicable): kernel-rt-2.6.24.7-72.el5rt How reproducible: Every time. Steps to Reproduce: 1. Install RHEL5.2 2. Install MRG RT kernel 3. Boot RT kernel Actual results: Kernel hangs after reporting amount of memory available (see attached console output). Expected results: Running kernel Additional info: Debbugging printk's indicate that the hang is occuring in calibrate_delay_direct(). Jiffies are not incrementing, so the calibration loop never terminates.
Created attachment 311759 [details] Boot log for LS21 lockup
I swapped the two LS21's that were in slots 1 & 2 and the failing blade (formerly in slot 1) reported double bit errors on DIMM slots 5 & 6, disabled the two slots and then booted on up. Here's a cut-n-paste from the web interface to the event log: 1 E BLADE_02 07/14/08, 21:07:55 (SN#YK10A269W03L) DIMM number 5 failed. 2 E BLADE_02 07/14/08, 21:07:55 (SN#YK10A269W03L) POSTBIOS: 289 Board 1 DIMM Pair 3 Double Bit Error. 3 E BLADE_02 07/14/08, 21:07:54 (SN#YK10A269W03L) DIMM number 6 failed. 4 E BLADE_02 07/14/08, 21:07:54 (SN#YK10A269W03L) POSTBIOS: 289 Board 1 DIMM Pair 3 Double Bit Error. 5 I BLADE_02 07/14/08, 21:07:25 (SN#YK10A269W03L) System Reboot
