On April 8, 2014, an updated SLES kernel was released that addressed this issue:

# uname -r
3.0.101-0.21-default

This kernel version is available through the normal update channels (nu.novell.com / SMT Server / SUSE Manager).

To download the kernel individually, use this URL:
https://download.novell.com/Download?buildid=X-K27cpMfVQ~


Prior to the release of this updated kernel, to resolve this problem the recommendation was to backrev to the previous kernel.  Those instructions are kept in this document (as seen below), but do not represent the suggested solution for this problem.


Backrev to the previous kernel, until and when a new kernel is available.

# uname -r
3.0.101-0.18-default

# zypper se -s kernel-default
This will list the available kernel versions in the update channel.

# zypper in --no-refresh --oldpackage kernel-default=3.0.101-0.15.1
Installs the older kernel. You will be prompted to backrev other dependent kernel packages. Select Solution 1 to downgrade your kernel.

# zypper in --no-refresh --oldpackage kernel-source=3.0.101-0.15.1
You will also need to downgrade the kernel source so applications that depend on the kernel can properly compile their kernel drivers. Again, select Solution 1 to downgrade dependent packages.

# reboot
The server needs to be rebooted to activate the downgraded kernel.

The kernel has been removed from the update channel and patch areas.
