Kernel soft lockup

Hello IPFire community

At first sorry for my bad English.

We have a 2 years old all time good running IPFire systems and since the last version (139), we have a problem with this. So that she stop working after a while (about a week later, after the last reboot). I have only found this bad things in the log file.

I have also upload the kernel log file from the first event of the lockup from one week ago that have more error messages by this event.

Is this a hardware problem or maybe a bug in the kernel and How can I check where I get this problem?

I don’t believe this is a kernel bug because core139 not change the kernel.
vfs_read errors sounds like a filesystem or disk problem. Is this a mSATA SSD or a SD Card?

Hi Arne,

It is a msata ssd, also tow years old and the io traffic is mostly from writing log events, but i have not see io errors in the log’s but maybe it is. I will check (buy a new one and than dd) this and than tell if this solution is fine.

Hi Arne, i have now swapped the ssd and also copy the IPFire-System with dd without problem. Now I will wait tow weeks and hope that that fix this.
