I doubled it and unfortunately the problem still happened within a few seconds:
[root@trimslice ~]# blockdev --getra /dev/sda
256
[root@trimslice ~]# blockdev --setra 512 /dev/sda
[root@trimslice ~]# blockdev --getra /dev/sda
512
[root@trimslice ~]# mount /dev/sda1 /mnt/boot
[root@trimslice ~]# rsync -xav /boot/ /mnt/boot/
Over on the serial console:
[ 1635.044729] hub 1-0:1.0: cannot reset port 1 (err = -110)
[ 1635.273814] hub 1-0:1.0: cannot reset port 1 (err = -110)
[ 1635.279207] hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
I tried slowing down the rsync with
nice -n19 ionice -c3 rsync --bwlimit=1024K ...
but that didn't help.
The good news is the SSD is ok according to the badblocks program.
