Extreme Slowness

Unread postby xtgk » Wed Dec 06, 2017 3:00 pm

Hi there, I have had my Odroid C2 for about a year now. Have had miscellaneous issues and can usually figure them out but this one has me stumped. I hadn't used my device for about a month in September from being out of town and when I booted it up, it was very slow. Like crawling. Sometimes it will take 15-20 minutes to go from black screen to login and even SSH can be really slow. In this case, the system is not really usable because of the lack of performance. I have continually upgraded the system in hopes of new updates resolving the issue but it has not worked yet.

The only things that pop out that I can see when I logon is several messages about uninitialized unradom read, that zram swapping is failing to initialize. I also noticed a lot of irqbalance messages in the syslog.

Here's some output for my system from uname and df.

Linux odroid64 3.14.79-115 #1 SMP PREEMPT Mon Jul 10 12:13:00 BRT 2017 aarch64 aarch64 aarch64 GNU/Linux

Any help is greatly appreciated.

Log-in screen should appear within ~30 seconds. Some portion of the root file system could be corrupted.

Did you update the system software with following steps?

Also check the CPU governor. If it is no "performance", try this command and reboot.
Code: Select all
echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils

If above items are not helpful, freshly flash the latest Ubuntu image.

I was missing that file, I think that resolved the problem. System is running as expected and much faster. Thank you very much.
