Oracle Linux 5.5 Issues Xen Warning: Domain attempted
WRMSR 0000000000000277 (CR 6902715)
This warning can be ignored.
10GbE PCIe Card in 8-Socket System with SLES11 Can
Cause Kernel to Crash (CR 6912821)
The kernel might crash in an 8-socket system with SUSE Linux Enterprise Server 11 (SLES11)
and a Sun Dual 10GbE I2 SFP+ PCIe 2.0. PCIe ExpressModule.
Workaround 1
Add the following entry to the /etc/modprobes.conf file:
options ixgbe InterruptType=1,1,1,1,1,1,1,1
It might be necessary to temporarily remove the Sun Dual 10GbE I2 SFP+ PCIe 2.0. PCIe
ExpressModule to prevent the kernel from crashing long enough for you to modify this file.
Workaround 2
Install drivers from Novell.
1. Navigate to the following page:
http://drivers.suse.com/driver-process/staging/pub/update/intel/sle11/
common/x86_64/
2. Download and install the following drivers:
intel-ixgbe-2.0.75.7-1.x86_64.rpm
intel-ixgbe-kmp-default-2.0.75.7_2.6.27.19_5-1.x86_64.rpm
