No network on Fedora 9 x86_64 follow up

Following my post related to NetworkManager. I have found out about the workaround. If you have x86_64 system with 4GB support enabled, you should disable it in order to make NetworkManager work. I am not sure if that bug affects other distributions so, possibly the bug may be related to the x86_64 kernel. Let see if my theory can be verified.

That's strange. I am using Fedora 9 x86_64 with 4GB RAM, and I don't have any problem with NetworkManager.

same here.

Currently using x86_64 with 4gb + networkmanager. No such issues.

Its a Thinkpad T61 with Intel 3945ABG wireless

Further investigation, it appears the bug is more kernel related than NetworkManager with the use of skge module. My system uses Marvell Yukon Ethernet integrated in the Gigabyte GA-K8NSC-939. Maybe the skge module does not support 4GB so I have submitted the bug for that reason.

I had the exact same problem with very similar hardware. Your post helped me get some ideas, I tried a bunch of different things. Did some packetsniffing etc.

Turns out it is something specific to the Marvell network card. I have two NICs on my motherboard and I tried the other one (Nvidia) and network seems to work perfectly! So maybe your problem could be fixed/worked around by trying a different network card.

I took an old Dlink Ethernet card, enabled 4GB RAM support on the motherboard and now runs Fedora 9. The issue related to Marvell network card about the 4GB RAM is confirmed thus definitely a kernel bug.

Fedora 9 x86_64 - The network icon next to my name and date always shows that there is no network available, and I usually have to manually restart networking a few times, click on the icon and enable and disable networking a few times, as well as fiddle with "work offline" back and forth in my Firefox browser. Sometimes it starts working quickly, other times I have to play with it for 10 minutes before I can reach the internet. Regardless, the icon always shows up as disconnected even if I am able to access the network. A search of the internet has not assisted me in my quest to resolve the issue. Can anyone help?

Could you provide your Ethernet card specification?

Good work people. I have a GA-K8NSC-939 + Athlon 3200+ and 4GB. I'm running Ubuntu 8.04 wuth an updated 2.6.24-17 64-bit kernel. I see the same problem.
When I upgraded from 2GB to 4GB, I went into the BIOS, Ctrl-F1 to get to the advanced chipset features, then enabled 4G RAM support. After that, when I booted I couldn't access the network. Interestingly, there was a boot-time message from the kernel
skge eth1: enabling interface
, so I didn't look there for the problem.


After reading the posts here I went back, disabled 4G support and got my network back - at the cost of a few hundred MB of RAM. The kernel now only sees 3584MB instead of the 4096MB it saw before.

Using AMD RX Vega driver OpenCL on Fedora 29

The Raven Ridge APU is very capable processor to handle OpenCL inside some applications like Blender, Darktable and Gimp. Unfortunately, the current implementation from Mesa, clover, stuck to 1.3, is not supported. AMD released their driver 18.40 with OpenCL2.0+ targeting only Red Hat Enterprise Linux/Cent OS 6.10 and 7.5 in addition of Ubuntu LTS. The good new is the former rpm format can be used on Fedora.

The graphical part of Raven Ridge is Vega 8, basically a cut-down of Vega56 or Vega64 meaning choosing either driver for RX Vega.
The instruction is provided for extracting the rpm files but here is
 some requirements for OpenCL:
kernel-devel (provided by Fedora repository)amdgpu-dkmsdkmslibopencl-amdgpu-proopencl-amdgpu-pro-icd Once done, applications needing OpenCL will automatically detect the driver located on /opt/amdgpu/lib64. Blender will list as unknown AMD GPU and Darktable will enable it.



There is a ROCm version but it currently does not support the graphical side of Rav…

Improving HP Envy x360 convertible on Linux: the missing accelerometer driver

If you own an HP laptop equipped with AMD processor, you may find out the auto-rotation will not work as intended. It turned out that sensor is missing a driver not currently available on Linux kernel using the lspci -nn command from the terminal

03:00.7 Non-VGA unclassified device [0000]: Advanced Micro Devices, Inc. [AMD] Device [1022:15e4] That driver in question is AMD Sensor Fusion HUB. Unfortunately, researching it turned out harder even on AMD own website. Bug is already filed without answer yet from one of AMD representative.

HP Envy x360 Convertible Ryzen 2500u update

Nearly one month later, HP Envy x360 Convertible 15  powered by Ryzen 2500U is running smoother on kernel 4.19.0 with someissues:
The LED for the mute button failed to work suggesting a possible ACPI issue.An unfortunate oversight from HP for not including a led for Num Lock button. The touchscreen function failed due to ACPI bug related to a mis-configuration of tables. Sadly, it affects all HP Envy touchscreen series equipped with AMD processors. Workaround made by an Arch user exists and no upstream Linux maintainers has picked up yet for clean up and improvment. The side effect would be an unfortunate false impression HP touchscreen with AMD processors is horrible.The gyroscope needed to automatically rotate the screen depending of the position is broken possibly due to ACPI bug.
On the positive side, I was impressed by the modular adaptability  of HP Envy x360 upgrade wise thanks to the excellent HP documentation. The board can be replaced with the powerful version of Ryzen 7 APU…
