The message:
    INFO: task gpartedbin:1832 blocked for more that 120 seconds
means that gpartedbin was an innocent victim and had to wait for 120
seconds inside the Linux kernel for disk IO to occur.

INFO: task blocked for more than 120 seconds.
https://helpful.knobs-dials.com/index.php/INFO:_task_blocked_for_more_than_120_seconds.


The attached kernel messages is full of errors for disk sdc.  E.g.

[   98.865768] scsi_io_completion: 41 callbacks suppressed
[   98.865779] sd 6:0:0:0: [sdc] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[   98.865787] sd 6:0:0:0: [sdc] tag#0 Sense Key : Not Ready [current] 
[   98.865793] sd 6:0:0:0: [sdc] tag#0 Add. Sense: Medium not present
[   98.865800] sd 6:0:0:0: [sdc] tag#0 CDB: Read(10) 28 00 00 00 00 00 00 00 08 00
[   98.865802] print_req_error: 41 callbacks suppressed
[   98.865805] print_req_error: I/O error, dev sdc, sector 0
[   98.865815] buffer_io_error: 38 callbacks suppressed
[   98.865818] Buffer I/O error on dev sdc, logical block 0, async page read


Given that the kernel is reporting hardware errors for sdc and GParted
is stuck waiting in the kernel for disk IO to complete, I don't see any
bug with GParted or anything we can do.
