Enabling Kernel edac AMD64 causes fuse segfaults
by selfprogrammed from LinuxQuestions.org on (#6DKVB)
Been working on bringing up this custom kernel for Slackware 15, kernel 5.15.
I have a huge kernel, from Slackware distribution.
I have a custom kernel, based initially off my previous custom kernel from Linux 4.4.
I have done this many times so I know how to migrate to a new kernel. I have been running Slackware and making custom kernels since 1997.
The last problem was that I needed to get a new webcam installed for a meeting.
Because of that I had to put support for v4linux into the custom kernel.
At the same time I looked around for other things, and noticed the EDAC.
I don't have ECC memory, but it seemed to support AMD64 (which I do have) and seeming to offer other things that it did not get specific about, but mention mce registers, which I do have.
So I enabled it. It was enabled in the huge kernel and was not causing any problems there.
I only enabled the EDAC that was AMD and made them modules, just like in the huge kernel from Slackware.
Been getting errors in dmesg and syslog ever since.
I run the old Linux 4.4 until I get this running right, and there are no errors over there, so it is NOT an actual memory problem. I run for hours and hours and have NOT seen new nor random faults.
These errors also do not affect this 5.15 system, even after running it for hours and hours.
The huge kernel does not keep module edac_amd64 loaded, but keeps the edac_amd_mce_something module loaded.
The edac_amd64 module loads with missing symbol error messages (edac_get_owner is one).
These would be satisfied by functions in edac_mc.c. The huge kernel does not get these error messages.
I cannot find where edac_mc.c code would end up.
I am configuring the kernel using menuconfig, and selecting normal EDAC selections.
Unless I am doing something wrong, there is a BUG in the kernel EDAC.
The story continues thus:
So, since the huge kernel does not keep edac_amd64, and after two more compile attempts I cannot fix this,
I decide to turn off the edac_amd64, and turn off the edac_amd76 module too.
NOW:
I notice in the logs that fuse has been having a NULL ptr and has been OOPS-ing.
I can see in the syslog, that this started exactly with the custom kernel with edac.
I am looking a dmesg now and see this message

[ 2127.369126] EXT4-fs (sda7): mounted filesystem with ordered data mode. Opts: (null). Quota mode: disabled.I only have the EDAC for AMD mce registers enabled now.
I could disable the EDAC entirely.
Either there is something wrong with the kernel compiling, or there is a kernel BUG in EDAC.
I don't know how I could configure a kernel using menuconfig and get this.
I am not looking for someone to tell me "just use that" to avoid the issue. I can get a kernel working.
This is about, what the hell is this, and what is going on.
There is the consideration that I also enabled v4linux in the same kernel compile. But, that has not been having problems. The webcam has not even been plugged into the USB for these EDAC tests.
Anyone recognize anything.
Do I keep fiddling with the kernel options, or upgrade the kernel to a newer version.
Did not want to be changing too much at one time.
I have a huge kernel, from Slackware distribution.
I have a custom kernel, based initially off my previous custom kernel from Linux 4.4.
I have done this many times so I know how to migrate to a new kernel. I have been running Slackware and making custom kernels since 1997.
The last problem was that I needed to get a new webcam installed for a meeting.
Because of that I had to put support for v4linux into the custom kernel.
At the same time I looked around for other things, and noticed the EDAC.
I don't have ECC memory, but it seemed to support AMD64 (which I do have) and seeming to offer other things that it did not get specific about, but mention mce registers, which I do have.
So I enabled it. It was enabled in the huge kernel and was not causing any problems there.
I only enabled the EDAC that was AMD and made them modules, just like in the huge kernel from Slackware.
Been getting errors in dmesg and syslog ever since.
I run the old Linux 4.4 until I get this running right, and there are no errors over there, so it is NOT an actual memory problem. I run for hours and hours and have NOT seen new nor random faults.
These errors also do not affect this 5.15 system, even after running it for hours and hours.
The huge kernel does not keep module edac_amd64 loaded, but keeps the edac_amd_mce_something module loaded.
The edac_amd64 module loads with missing symbol error messages (edac_get_owner is one).
These would be satisfied by functions in edac_mc.c. The huge kernel does not get these error messages.
I cannot find where edac_mc.c code would end up.
I am configuring the kernel using menuconfig, and selecting normal EDAC selections.
Unless I am doing something wrong, there is a BUG in the kernel EDAC.
The story continues thus:
So, since the huge kernel does not keep edac_amd64, and after two more compile attempts I cannot fix this,
I decide to turn off the edac_amd64, and turn off the edac_amd76 module too.
NOW:
I notice in the logs that fuse has been having a NULL ptr and has been OOPS-ing.
I can see in the syslog, that this started exactly with the custom kernel with edac.
I am looking a dmesg now and see this message

[ 2127.369126] EXT4-fs (sda7): mounted filesystem with ordered data mode. Opts: (null). Quota mode: disabled.I only have the EDAC for AMD mce registers enabled now.
I could disable the EDAC entirely.
Either there is something wrong with the kernel compiling, or there is a kernel BUG in EDAC.
I don't know how I could configure a kernel using menuconfig and get this.
I am not looking for someone to tell me "just use that" to avoid the issue. I can get a kernel working.
This is about, what the hell is this, and what is going on.
There is the consideration that I also enabled v4linux in the same kernel compile. But, that has not been having problems. The webcam has not even been plugged into the USB for these EDAC tests.
Anyone recognize anything.
Do I keep fiddling with the kernel options, or upgrade the kernel to a newer version.
Did not want to be changing too much at one time.
