Enforcing IO size to 512 bytes does help. That is why I ever have paid attention to buffer location variations. > I still wonder if we could determine the size of corruption - note, we ca= n increase the buffer area in BSS for test purposes. Increasing bio_buffer size to BIO_BUFFER_SIZE*4 didn't help. Trying to work out with the bd_io_workaround() and the comment about it and= to detect possible buffer overrun... --=20 You are receiving this mail because: You are the assignee for the bug.=
