Apparently SD Card readers and forks don't mix...
....who would have thought?
I recently installed Ubuntu on a computer at a local bar as the XP install
went down the crapper. We were having some minor weird issues though with
the touchpad randomly behaving really weird. Mouse cursor jumping, clicks
when there shouldn't be clicks, etc. Plus the machine overall was too
slow.
So after playing around with it for a while, and looking in the error
logs, I discovered the problem. The system was hammering the SD card
reader every few milliseconds trying to deal with a card it thought it
was inserted. No card was inserted though.
So when I spoke to my friend who owns the bar about it, he did mention to
me that someone used an SD card and couldn't figure out how to remove
it..so he used a fork to force the card out, bending and destroying pins
in the process. Needless to say some pins were touching and causing the
above problems. Once I moved the bent pins out of the way, machine became
100% trouble free.
Now my question is, is there any way to permanently disable the SD/MMC
card reader? So that if someone tries to insert a card, or if the pins
happen to randomly touch again, the problem does not re-occur? The problem
doesn't happen until Ubuntu actually activates the reader (as indicated by
the status LED of the reader). So if Ubuntu doesn't activate the reader
and just ignores it, the pins can touch all they want...won't be an issue.
Google hasn't been much of any help as all references on google deal with
trying to get SD card readers working, not with disabling them. =)
I already tried to blacklist some SD card related modules while the
problem was still occurring before actually resorting to physical means of
unbending pins, but no matter what modules I blacklisted it didn't make a
difference.
Thanks,

Who indeed? Any sane person.

Since this is a bar computer apparently accessible by zanykooks, while
you/we are working on the cardreader problem, we should also be sure to
prepare for the possibility that someone is going to jam an electronic
cattle prod or a taser into the USB port.

I would be tempted to squirt a load of epoxy resin into the slot to keep the
pins where they are and then blank off the front to stop anyone trying to
use it and fubaring their card, or at least unplugging the leads from the
mobo - if applicable, or both.
I presume the reader is integrated rather than one of those front panels
that fit into a spare drive bay so cant be completely removed?

I've had a similar thought myself as well.

Yea it's a laptop actually so to get at the card reader I'd need to take
the whole laptop apart...

Disabling the various services that operate this slot is probably not
going to prevent the physical short circuits that happen to upset the
computer.
So I would look at /only trust a more permanent solution like glueing
something in the slot.

Thanks for the links but unfortunately there is no such bios option for
this machine. Matter of fact, I don't think I've ever seen a bios with
fewer options...I was wondering why they even put a bios setup in there to
begin with.

While I do agree with you, it's not my own computer so I don't know if
he'll want to do that.
I'll most certainly suggest it though. =)

The Incredible Shrinking BIOS. (:
Apologies in advance if this has already been suggested, but you might
want to take a look at the man page for setpci. I hope it helps!
