It's the first time I touch this code, but I will learn from the code and try to find it out... but still in hope to find a clean solution... If size stored on partition table is really larger than disk, my guess it will cause I/O errors, and that some disks may get crazy like you pointed. Do you think disk could cause kernel instability? I think it is acceptable if no consequences to kernel stability, since it is a "specific-device" workaround.
