Kernel Panic & memory problems #1

Closed tbludau closed 6 years ago

tbludau commented 6 years ago

Hello,

i've identified on all my systems with the Asus XG-C100C PCIe/XG network card and the atlantic driver a lot of strange problems under Ubuntu 16.04 and 18.04 (lts) with the newest kernel versions. ( 4.15.15-041515-generic, 4.15.16-041516-generic, linux-image-4.15.0-13-generic)

So i've updated to the newest driver 2.0.6. but the problems are still there.

After a short time when some traffic is comming over the network i got a lot of messages with: "general protection fault: 0000 [#3] SMP NOPTI" with a call trace and randomly a lot of programms and modules (samba, ext4, network, etc.) crashes and randomly the kernel crashes too. I searched a lot of time where this problem is coming from and identified the atlantic driver as source of the evil.

Under Windows (dual boot system) everything works normal. modinfo-atlantic.txt

crash-4.15.15-041515-generic.txt crash-4.15.16-041516-generic.txt

On RedHat they identified a equivalent problem some month before.

When you give me some hints what you need for debugging i will send you everything.

The Sytems are: AMD Turion(tm) II Neo N54L Dual-Core Processor and AMD FX(tm)-8120 Eight-Core Processor

Thanks for reporting this! Could you please give us your sudo hwinfo output?

tbludau commented 6 years ago

I send you the hwinfo over mail.

At the moment i've created a stable enviornment.

The problems i've described were definitly a problem with the drivers from the delivered kernel version (1.6.13.0-kern). And after some compiling and tests i think i forgot to integrate the module in the initrd and used the old one.

So this is the second time i have this stable state. At the moment everything looks as expected. (with a bug of the link detection on the N54L System and driver 2.0.6, but thats another problem)

cail commented 6 years ago

So... 2.0.6 which is here has no this issue visible?

tbludau commented 6 years ago

After some Network-Traffic tests i never seen this issue again with 2.0.6.

So this can be closed too.
