Should that be forwarded to IBM?
As far as I remember, IBM is aware. KCSAN practically doesn't work on s390x, i.e. shows way too many false positives. I hit this when I tried to debug certain memory issues on a LinuxONE machine. It's definitely on my radar, but I don't think it's a priority for anybody right now. However, it's a real problem, so I don't want to close the bug without any meaningful resolution. At the same time I doubt it will be fixed anytime soon. -- You are receiving this mail because: You are on the CC list for the bug.
