[snipped] Hi Rolf and Thorsten, I run the following workloads for 48+ hours, no panic or data corruption so far, - tar, untar, gzip, gunzip - git clone/fsck/gc/archive - copy iso files, checksum calculation and check for all the iso files - kernel source code compiling - ext4 file system check The fix might not be perfect yet, but IMHO we should provide a fix now. If there is any other known issue triggered, let's fix and verify later. Thank you all for the testing and verification these days. Coly Li
