The dmesg contains: [ 538.728064] EXT4-fs warning (device dm-0): ext4_end_bio:316: I/O error writing to inode 23330865 (offset 0 size 8388608 starting block 812628)
An 8MB transfer will need at least 128 ring entries (TRB) even if the request
is a single contiguous memory block.
Are you using the patch that increases the ring size from 64 to 256?
