Same issue here with 5.0-rc1 and rc2. I dont have kernel paging request at that adress but the same error pops out. BUG: unable to handle kernel paging request at ffffa18f00099000 Then a lot of "corrupted low memory at" messages. System stays up and running and is usable in TTY but GNOME stays frozen with only mouse cursor moving. I reported This bug earlier also. Here is bug ID 202247. This makes the PC unusable for watching any video because it frezes at some point.
Created attachment 280495 [details] DMESG. Full dmesg of the issue.
Also as i see in the log BOTH of our machines run btrfs. And as it seems so far this bug occurs only with BTRFS filesystem.
I am not using btrfs, but ext4. 0000100000000008 looks like some bitmask found at the wrong place, but ffffa18f00099000 appears to be some address-like construct. The stack traces look very different, too, so I am pretty sure these are 2 separate problems. Haxk20, would you mind to open your own bug report? Thanx

Thanx Actually i opened an bug report 2 days before yours and still no response to that issue. Im sure they are busy but i really hope this gets fixed in later RC builds because i cant work with freezing machine. Will test linux-next branch to see if it already has a fix because that very possible.
OK my issue is fixed in linux-next.
Congratulations
Would it be possible that anybody looks into this bug report?
I'm closing this due to lack of interest
