I can, but I was hoping to get some pointers from the maintainers to quickly get down to the culprit. I will run 'git bisect' later when I get a chance, would greatly appreciate it if someone hints me towards possible culprits. I should probably also mention that the kernel seems to be fine with physical removal. Only when I do soft removal: sysfs echo 1 > remove seems to cause the issue. Thanks,
