I am using: IPFire 2.27 (x86_64) - Core-Update 174
my new ipfire hardware is a Ryzen 5600G apu
https://fireinfo.ipfire.org/profile/782d109b426be6ed9859d73c24bf5e7187912432

what am I missing

People earlier in the thread had the problem with their nic driver resolved by the update to kernel 5.15.35 in CU167 from 5.15 in CU162.

Others still had the problem with that kernel version but have not reported back about the problem continuing as newer kernel versions have been released.

We are now on kernel 6.1.11 in CU174. In between there have been 5.15.71 in CU171, 5.15.59 in CU170 and 5.15.49 in CU169.

If you didn’t see it when you upgraded 3 months ago but do now with CU174 then it sounds like a new bug has been introduced into the nic drivers in the kernel for either your Nextreme or Realtek nics.

Unfortunately all we can do is wait for the next kernel update and see if updated drivers have been supplied to the kernel developers and hope that those fix the problem.

From previous threads in the forum on the BUG: KFENCE it looks not to affect functionality as this is the kernel stopping the driver from re-using memory space it has said it no longer needed, so the driver has to request new memory space.

Thanks @bonnietwin ,

I check in my log and the first time I see it is on second of march.

At that time it look like this:

Before with the same hardware no problem.

Also I notice in the log that two days later it didn’t give problem for 3 days and then boom its back.

2-03-2023 is a just after core 173, maybe that info help?

is there something I can search or so? if yes, let me know I will search for it and report.

Best regards

This is a totally different kernel error than your first reported one

The BUG: KFENCE error was being seen multiple times and is related to one of the NICs.

The earlier kernel error was seen only once and is related to the AMD p-state driver for CPU Frequency control mechanism similar to the Intel p-state driver for their cpu chips.

If this error only occurred once and is not seen again in the logs then I am not sure I would worry about it too much. It looks like an error was reported when it tried to do something with enabling the p-state.

If the same kernel error occurs more frequently then hopefully other people are experiencing the same problem and have reported it as a bug to the kernel/amd p-state driver developers and a fix is released in a future kernel update.

The only other option would be for you to report it upstream into the kernel bugzilla.

Doing a search on the internet did not flag up that specific kernel error.

CU173 is when the kernel 6.1.11 was introduced. However I have no real knowledge about the kernel and can’t say what might be causing the problem you are seeing.
@arne_f do you have any input on this?

Thanks @bonnietwin , I checked and I have the AMD error on: 2, 9 and 16 of march, the kfence i have the rest of the days but some days are no error.

I dig deeper to find out the exact day that I upgrade to the new hardware, and it was on 18 of march and not 3 moths ago as I was thinking, sorry for that.

would it help if I on assign the realtek nic as its more as a backup nic, and leave the nextreme on?

this because before I didn’t have the error so much with the old hardware but with this one (realtek) on the new motherboard look like giving some problem.

I will give it a try later on.

Wat els can I look for ? or what am I missing ?

The amd pstate and the use_after_free are two different problems.

The use_after_free looks like a bug in the broadcom driver. But it could also a more basic protocol handler.
I know that such an error is fixed in kernel 6.1.13 but IPFire should not use the mpls protocol.

The amd pstate tries to access an unsave marked processor status register so the kernel prevent the access. Not sure if this is a bug in the kernel internal acl or the driver.

Have you a spare ssd and can try the unstable update which update the kernel to 6.1.24 ?

@arne_f thanks Arne, If I am not mistaken, I have a free hdd in the box, my only thing is the amd pstate error was done with the old hardware,its a litle dificult to put that back in action, I will check in the wekend what I can do and report back , the new hardware is also amd but i did not see the error yet.
