Installation DVD missing EFI support
Hi. The installation DVD (SL-64-x86_64-2013-03-18-Install-DVD) has /EFI/BOOT directory, but it's missing the important .efi file. Thus, the DVD isn't recognized by UEFI firmware as EFI capable booting media, and it can be booted only using legacy (BIOS) booting. That's making further problems, because according to https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/ch-Boot-x86.html: Therefore, the installed system must boot using the same firmware that was used during installation. You cannot install the operating system on a system that uses BIOS and then boot this installation on a system that uses UEFI. Therefore, Anaconda assumes that the system isn't UEFI, and makes wrong decisions, which cause SL to not boot, until manually hacked. Thanks, Zvika
Network dies unexpectedly
Greetings, I administer a web server for my institution and last night we had a problem. The server is a 1U Intel Xeon E5620 machine. The on-board network interface is an Intel 82574L Gigabit Controller. Scientific Linux 6.4, kernel 2.6.32-431.1.2.el6.x86_64. At some point last night the network interface stopped working giving a backtrace on dev_watchdog. I could not restart the service network, it complained that the interface eth0 was not available. I tried to reconfigure it with NetworkManager, unsuccessfully. A full system reboot fixed the problem, although I couldn't identify the problem. I do not know if this matters, but this problem never occurred before the last yum update.

Re: Network dies unexpectedly
This was caused by an internal hardware watchdog built into Intel network cards, it detected an error and disabled the interface on the hardware level until you rebooted and the cards memory was cleared. It looks like the card may have lost clock sync with its neighbor which is odd that basically means it wasn't sending out the 5 volt signal used for frequency sync. I've worked with Intel cards for probably over a decade and Ive never seen this exact error before. Try rolling back to the previous kernel version however this looks more like it may be a physical hardware issue.
