Hi, I'm mounting an ext4 filesystem residing on an AHCI SATA disk via loop: losetup -o 64424509440 --sizelimit 34359738368 /dev/loop0 /dev/sda mount -t ext4 /dev/loop0 /mnt
Works perfectly on <= 4.4.155 (latest version on 4.4.x longterm branch) On 4.9.126 (longterm branch) I get these errors: blk_update_request: I/O error, /dev/loop0, sector 23778144 blk_update_request: I/O error, /dev/loop0, sector 23789056 blk_update_request: I/O error, /dev/loop0, sector 23791038 ... On 4.14.69 (longterm branch): print_req_error: I/O error, /dev/loop0, sector 22685550 print_req_error: I/O error, /dev/loop0, sector 22696582 print_req_error: I/O error, /dev/loop0, sector 22675034 ... and even on the latest stable 4.18.7: print_req_error: I/O error, /dev/loop0, sector 21044836 print_req_error: I/O error, /dev/loop0, sector 22058444 print_req_error: I/O error, /dev/loop0, sector 22858336 ... That's 100% reproducible on all my computers. They are amd64 desktop PCs running unpatched vanilla kernels from kernel.org. Any ideas? I can provide more details if requested (.config, dmesg, etc.) Thanks in advance. -- Gergely EGERVARY
