is that a Dell card?

The previous kernel version boots fine and everything works just well, but the latest kernel (v2.6.32-431.17.1.el6.x86_64) cannot boot and Grub says something like "trying to reach blocks outside of partition" and that's all the message there is and boot hangs.

If it's really Grub saying this, the kernel hasn't even started. Is /boot a separate partition? Size and fs? Have you fsck'ed it? Checked free space and inodes? Tried to reinstall the kernel and the initramfs?

Curious,

The USB devices seem to lose connection from time to time (UPS and USB disks). And when this happens, they cannot be used anymore. A full reboot is needed before I can connect and use an external USB disk for example. Without reboot, the device just doesn't show up in /dev. I found error messages in the log as below:
