Hi everyone,
I have a Dell Latitude 5480 laptop with a Fedora 36 install. It crashes
regularly, uptime can sometimes be less that 5 mins but sometimes it
lasts several hours. There is no trace at all in journalctl of its
demise. It behaves like a machine with a memory issue. I've moved the
memory from one slot to another and cleaned the connector.
I've been using Redhat style systems for over 20 years and have known
uptimes of several years. This laptop also boots Win10 and that install
is stable. The machine passes Dells internal diagnostics. I'm travelling
this week and don't have access to memtest86, but the Win10 memory test
passes. Once I'm back home I can network boot it and run memtest86 and
FC36 live - which will eliminate the ssd & its controller from the picture.
.
This machine has a KabbyLake processor (Intel Core i5-7200U 2.50GHz), 8G
memory, an Intel i915 (HD Graphics 620) GPU and SSD storage. I've read
on various forums that this combination of CPU/GPU can be problematic
and some mentions that an upcoming Kernel release may contain a remedy
for this.
In addition to the FC36 standard kernel, I have tried a 6.0 kernel build
and even the development 6.1 kernel from Rawhide's daily builds ( Beta
for FC38 ) and its related firmware RPM. Also tried loading the 5.11
kernel from FC34. All with the same results. In fact the FC38 beta
kernel only survives a few minutes even without the GUI.
Is this hardware faulty, despite Win10 being stable? Does the Linux
install stress the hardware in a way Win10 doesent. Should I hold on
for a later kernel release with a fix.
Is anyone else experiencing this issue? I'd value any insights.
Many thanks
Ken
Ken-
You should probably grab the kdump and post a BZ at http://bugzilla.redhat.com and maybe a kernel engineer can dig into the issue further.
Here is a document on how to use kdumps
