I'm still testing here. There are some still some issues with newer kernels= on sun4u with the code crashing in ext4, but I'm going to perform stresstests = with a patch 4.19.325 kernel now. I will also try to bisect the other crash regression in sun4u that was intr= oduced sometime between 4.19.x and 6.x. Adrian --=20 .''`.
