It was upon installing a fresh Ubuntu Minimal. In my case, the blinking cursor was all I would ever get. I found a few vague references to rolling over of logfiles at boot time being the cause. Oct 11 23:21:48 linux rsyslogd: exiting on signal 15. Oct 11 23:21:48 linux kernel: Kernel logging (proc) stopped. Oct 11 23:17:21 linux kernel: ondemand governor failed, too long transition latency of HW, fallback to performance governor I should mention that the ondemand governor failed message happens on successful boots but the other two don't appear to. but figured I'd put it up here in case anyone can help and wants to earn themselves some points. I'm going to do some research on Google etc. It looks like I've captured a recurrence of this issue, I copied the messages file and the dmesg file and had a look where processing seems to have stopped and found the messages below. It's been a while, mainly because my server has been up for a long time. The fact that it is intermittent is what confuses me.Īny pointers on diagnosing the problem would be much appreciated. Has anyone any guidance on how to diagnose this issue or what the cause is likely to be? Normally I need to press the reset button to reboot the PC and often it will reboot fine. From what I've read, this blinking cursor screen is presented by Ubuntu itself and not Grub, so I assume the boot process gets halted for some reason. It gets past Grub and then stops at a blank screen and blinking cursor. Occasionally my Ubuntu 10.04 PC won't boot properly.
