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. All the former kernel versions worked fine. Could there have been a change in the modules handling the raid controller? I've got another issue as well that regards the previous kernel that I'm using now (v2.6.32-431.11.2.el6.x86_64) instead of the latest one. 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: kernel: usb 2-1.1: ctrl urb status -75 received kernel: usb 2-1: clear tt 1 (8030) error -110 Has anyone encountered issues like that? I'd appreciate opinions on how to track further down the problem. Thanks! Andras
