James, could you pick up this fix, preferably for 3.10, please? I am not the only one you has run into the issue: https://nazar.karan.org/blob/distro! parted.git/8780c767126938173f49dfbcd4360813932f7756/SOURCES! disable-t9020.patch Thanks, Martin Both start_sect and nr_sects in struct partition are __le32 and require cpu_to_le32() on assignment. Without this fix tools like fdisk show an invalid partition table for SCSI devices emulated by scsi_debug on big-endian architectures, like s390x. Besides a kernel message like this was emitted: sda: p1 start 536870912 is beyond EOD, enabling native capacity sda: p1 start 536870912 is beyond EOD, truncated For verification 'xxd -l 512 /dev/sda' has been used to make sure that this fix makes scsi_debug generated partition tables on s390x look like the ones generated on my laptop.
