Summary: unable to handle page fault for address - EIP:
khugepaged
Product: Memory Management
Version: 2.5
Kernel Version: 5.9.1
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1

Thanks. That's a strange looking trace. I'll optimistically cc some
people who have been working in that area lately.
What caused this kernel to be tainted?
I always use hibernate.
I also use firefox with some tabs and it uses a lot of memory. (I have
a 4 Go laptop)
I have a lot of bugs when I resume.
This bug arises when I resume.
The first occurence in syslog is in march :
