Computer issues...

My primary computer had a sudden failure yesterday. I was working, I
turned around to grab something, and the whole thing just powered down
while I was looking away. I tried everything to power it back up, but
nothing worked.  However, it wasn't *completely* dead because two LEDs
on the motherboard came on, just nothing else. So, I started to pull it
apart and do some investigation. I pulled another power supply and
plugged just the motherboard into it, and viola, it came up. So, I guess
the 12v rail on my other power supply died. I went to Best Buy to buy a
new power supply (the one I tested with really wasn't big enough for
this machine), bring it back home, and got to work replacing the entire
power supply.

I happen to always buy fully modular power supplies if I can, so I was
in the process of swapping things out, and I didn't realize I had
plugged a Corsair modular SATA power cable in the SATA connector on the
new power supply and ran it to the bank of 4 SSDs I have in my main
computer.  Until I powered the new EVGA power supply and immediately
heard some odd crackling followed by the unmistakable smell of magic
smoke (quite strong I might add).  So, moral of this story is, while the
EVGA and Corsair modular connectors for SATA power cables use identical
physical connectors and will happily plug in on each other's power
supplies, how they wire them up most definitely is *not* identical, and
all four SSDs that were plugged into that modular SATA power cable are
now toast.  This includes my primary workstation and all data that was
on it.  Fortunately, I keep backups and what not, but I am currently
sending this email from my laptop and I will likely loose the next day
to two days to the task of reinstalling from scratch, then restoring
from backup (even as I write this, my laptop is writing a Fedora 27 Beta
USB boot key).  Joy!

Hi Doug,

Thank you for keeping us in the loop, as far as I can see there are no -rc
material except this one: https://patchwork.kernel.org/patch/10032391/

This patch is extremely important to forward to Linus in this cycle,
before -rc is closed, because NLDEV was added in v4.14 merge window.

Will it be OK from you side if I forward this to Linus immediately?

Thanks

Yeah.  Linus, as you can see from the story quoted above, I'm busy
rebuilding my primary workstation after frying four SSDs (doh!).  I've
reviewed the patch Leon is referencing here and I'm fine if he sends it
to you, or you can wait about a day or so and I can get it to you
(reinstall is done, now working on the restoring of backups, should be
mostly normal by sometime tomorrow).

Thanks Doug,

I'll send it on Wednesday evening, so if you restore before and will be
ready to do it by yourself, just drop an email to me and I'll skip this
pull-request exercise.

Ok, Leon, send me the patch directly, and I'll pick it up.

The story of what I had to do this last week is worthy of telling over a
beer some time.  Suffice it to say, I'm mostly back up and operational
at this point.

The "I have backups" turned out to be "I have backups that are looking
right now like they are 2 years old" until I found the root cause and
was finally able to get to the current backups.

And there was another incident and another drive got fried (I will never
buy mixed brands of modular power supplies ever again).

And I shipped the two drives that were actual rotational drives (I
originally said four SSDs, I was incorrect in that, I had forgotten that
the 4 drive caddy that got fried was actually 3 SSDs and one laptop hard
drive, then the 5th drive to get fried was a 3 1/2" internal sata drive)
off for possible controller replacement (not to the manufacturer, but to
a company that specializes in replacing bad controller boards for a flat
rate fee), but they didn't have any spare boards to fit my 3 1/2" drive,
they said it was too new and there was no inventory on its controller
yet.  Still waiting to hear on the other one.

And even if they have a controller board, there's no guarantee that any
data on the drive will be retrievable, thanks to my 4 year old.  He was
home sick with strep throat last Thursday, but I'd given him some
tylenol and his antibiotic and even treated him to a small mocha from
starbucks (yes, he likes chocolate flavored coffee), and I had
inadvertently forgotten to get him decaf, so he was full of energy and
happy, and I was sitting at my computer printing out the paperwork to
ship off the two rotational drives, and he says to me "Daddy, these work
really well here!" and I look over and he's got two magnets off of the
kitchen refrigerator and each hard drive has one magnet sitting on its
metal top cover.  So who knows if those things are even recoverable at
all at this point.  This happened *before* I found the root cause to my
missing backups.  So you can imagine how happy I was when I saw those
magnets :-/.

Anyway, I'm going to be processing patches over the next few days.  I
didn't want people thinking that I wasn't aware of the time and the
upcoming merge window, I'm still tracking it as best as I can while I
rebuild everything ;-)
