The system intermittently stops responding with the
Matrox G200eW graphics adapter
Description Systems using the Matrox G200eW graphics adapter might stop responding when the system starts.
Workaround Download and install the latest driver version from Dell.com/support/drivers.
Cause This issue is caused by a bug in the video driver.
Switching to text mode from GUI mode does not work with
UEFI
Description On systems with Matrox G200eW graphics adapters, the display flickers and goes blank when you switch to text
mode by using Ctrl+Alt+F1 or switch to run level 3.
Workaround Download and install the latest driver from Dell.com/support.
Alternatively, you can use the VESA driver to work around this issue.
Cause This issue is caused by a bug in the Matrox mga video driver.
IPMI may not start on systems that boot through UEFI
Description
The IPMI kernel modules might fail to load on systems that boot through UEFI. As a consequence, services that
depend on IPMI may be affected.
Workaround Add the line to/etc/modprobe.conf before starting the IPMI service:
options ipmi_si type="kcs" ports="0xca8" regspacings="4"
This issue will be fixed in a future release of SUSE Linux Enterprise Server 11 kernel update.
Cause This is caused due to a kernel bug that sets the IPMI driver to use the Block Transfer (BT) interface instead of
the KCS interface.
iSCSI login through BCM57710 over IPv6 fails
intermittently with Dell EMC EquaLogic targets
Description
iSCSI initiator login to an iSCSI target, through a Broadcom BCM57710 over IPv6, may fail sometimes due to a bug
in the kernel's TCP/IP stack. The login failures are more prominent with a Dell EMC EquaLogic target.
Workaround Disable Load Receive Offload (LRO) using one of the following methods:
• To disable LRO during boot or installation, pass it as a parameter during boot to the kernel command line by
typing the command bnx2x.disable_tpa=1.
• To disable LRO on a running system, type the following command at the command prompt # ethtool -K
<eth-interface> lro off
• To disable LRO during subsequent reboots, add the line options bnx2x disable_tpa=1 to the /etc/
modprobe.conf file.
This issue will be fixed in a future release of SUSE Linux Enterprise Server 11.
Cause The issue occurs when the group IP address of the Dell EMC EquaLogic storage is redirected to other IPs within
the iSCSI SAN for better load balancing.
With other iSCSI targets, retry attempts to login to the single IP address succeed, and do not cause login failures.
