Bug report

Since more releases of the kernel, I’ve got a violent hang (complete shutdown of the computer).
I managed to find the kerne trace:

I was wondering we was the right place to post this kind of problem ?

Best regards,

That looks like a bug in the wl module. That’s a Broadcom driver, right? Where did you download it from?

I use a Dell Vostro 3640 (an old laptop) and I installed the broadcom driver via fedy.

It is probable that the driver came from rpmfusion

Sure. This looks a lot like x86/retpoline: Ensure default return thunk isn’t used at runtime from last week.

There are similar reports from Arch Linux and other distros.

So, I have a Lenovo Yoga Pro 9i 16IMH9. I’ve been experiencing the same instability (kernel hangs) recently and see similar stack traces:

  1. Is there some bugzilla we can subscribe to for tracking the issue?
  2. I am actually on SilverBlue. Is there a way to revert to a specific image before this change? A month or so ago my laptop used to be stable…

Is there somebody from rpmfusion on this list ?
As far as I understand, the bug has been found. Maybe there’s a patch for this one.
The package for this driver is provided by rpmfusion. So, an update is welcome (if the patch exists) :slight_smile:

rpmfusion: Reporting Bugs. Problems with wifi are not unusual, so I have found it important to have a USB wifi dongle for use when on-board wifi is broken.

Thanks for the link. I will try to fill a bug report ASAP.
I think I’ve got a wifi usb dongle somewhere … :slight_smile:

Thank you @ycollet. Once you’ve done this can you please share the bug report? I’m not sure what module/package is being referred to, but hopefully I can learn so that I may be able to file bugs in the future.

I’d order a USB dongle just to see if this problem goes away when using that. I wonder what brand should I prefer for true OSS drivers though? I would not want to end up in the hilarious situation where I buy a dongle that uses the same driver! :slightly_smiling_face:

Come to think of it, my laptop seems to have an Intel Wi-Fi and it is my impression that Intel is quite good with OSS drivers?

Can somebody point me a kernel supported Wifi USB module I can buy on amazon ?

Some wifi chips have support for older kernels, but without vendor support they are often fall behind when newer kernels appear, see: https://github.com/morrownr/USB-WiFi/issues/314.

Don’t buy USB WiFi unless the vendor provides the USB ID and you confirm that the ID is supported by linux.org “in kernel” drivers, easily checked using https://linux-hardware.org/?view=search&vendorid=2357&deviceid=011E&typeid=net%2Fwireless#list by editing the ID’s in the URL. You can also try a “site” search: site:https://linux-hardware.org/ vendor part-name.

Thanks a lot for these information. I will check first to build the driver for this last WIFI driver. There was a ticket in:

If it doesn’t work, I will check for a new dongle.
