I have a Dell Precision M7510 laptop running Debian Stretch (installed August 2016),
with an Intel Pro 2500 series 2.5' 256GB SSD (part #SSDSC2BF256A5).
The root partition is EXT4, and the boot partition is EXT2.
Recently (after June 24, 2017), the laptop has been experiencing SSD IO failures when it is not plugged in,
which make the machine unusable.
I have appended below the dmesg output when the adapter is unplugged then plugged in.
When it is plugged in, there are no disk issues whatsoever; fsck, badblocks, and smartctl all report a completely healthy disk;
the output from smartctl is also appended below.
I have tried downgrading the kernel, from 4.9.0-3 to 4.9.0-2, 4.7.8-1, and 4.6.4-1, with no effect, so it is definitely not a kernel regression.
The failure happens both when laptop-mode-tools is enabled and disabled.
I would appreciate any help in identifying the cause of this failure and hopefully fixing it.
