Please post your driver to the linux-block list, and test a recent kernel.

Hello,
We are registering bio size of our device with linux kernel with below
available kernel API. blk_queue_max_hw_sectors(dev->osdev.queue,
(dev->aggr_max_size >> KERNEL_SECTOR_SHIFT));.
Max size of bio that our block device can handle is 106496 bytes (104KB) but
linux block device is
