Description Garry T. Williams 2007-07-08 10:43:49 EDT
Description of problem:
At boot, module tifm_7xx1 claims to detect a card.  There is no card inserted. 
(This is a mild irritation because now suspend/resume complains about it.)

Version-Release number of selected component (if applicable):

How reproducible:
Always on boot.

Steps to Reproduce:
1. Boot
Actual results:
Message kernel: tifm_7xx1: sd card detected in socket 0

Expected results:
No card detected in empty slot.

Additional info:
Machine is Sony Vaio VGN FS640/W.  No such problem on FC6 w/latest FC6 kernel
about one month ago.

Comment 1 Christopher Brown 2007-09-17 17:12:16 EDT
Hello Garry,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.

I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.

Comment 2 Garry T. Williams 2007-09-17 18:51:37 EDT
Thanks for the attention.  :-)

Yes, the bug is still present with  The indicator for me is an
LED is turned on to indicate a card present.  The log message now is:

    tifm_core: MMC/SD card detected in socket 0:0

Again, the only problem is the LED light turned on and the message that I cannot
remount external storage after waking from suspend to memory.  I have no card to
insert into the slot and don't plan to acquire one, so I doubt that there is any
other problem I will see as a consequence of this bug.

If I can help with any other diagnostic information, please let me know.
Comment 3 Christopher Brown 2007-09-18 04:33:37 EDT

# echo "blacklist tifm_core" >> /etc/modprobe.d/blacklist

which should stop the pesky module from loading at boot. However if you could
post output from lspci -vvxx I'd be intrigued to see what it thinks is the TI card.

Cheers Garry. Here it is:

1394a-2000 OHCI and SD/MS-Pro Controller

I need one last bit of info. Can you attach the output of lsmod as well.

and your troubles should be over. Then remove the blacklisting when 2.6.23
arrives and re-try.

Comment 8 Garry T. Williams 2007-09-18 18:17:00 EDT
I disabled the module by adding this to /etc/modprobe.conf:

    install tifm_core /bin/false

Now the laptop boots without turning on the LED and will suspend and resume
without the warning about the non-existent card not being remounted.


I will re-try on the .23 kernel when it's available and post an update to this bug.
Comment 9 Garry T. Williams 2007-10-13 10:15:52 EDT
I removed the "install tifm_core /bin/false" from /etc/modprobe.conf and
installed the 2.6.23-1.fc7 kernel from updates-testing.

dmesg shows:

    tifm_core: MMC/SD card detected in socket 0:0

The LED is turned on and after a resume from suspend to memory, I receive a
message (unable to remount (all) external storage media) from the KDE desktop.

I will continue to use the work-around (disabling the load of the module).  The
desktop message upon resume continues to show up in spite of disabling the load
of the module.  The LED is turned off, though.
Comment 10 Christopher Brown 2008-01-09 10:58:47 EST
Hello Garry,

Are you still having to disable the tifm_core module to sus/res with the latest
kernels? Any chance you can try 2.6.24 and report back when it arrives?
Comment 11 Garry T. Williams 2008-01-09 17:20:04 EST
Yes, the LED still turns on.  I still get a desktop notification 
"unable to remount..." after resume from suspend to memory.

I have just been ignoring all of this but, to be complete, I get this
behavior with and I see no later kernel in
updates-testing.  As soon as I can install the 2.6.24 kernel, I'll
test again and report back.

Just in case it's relevant, here's my latest dmesg.
Comment 13 Christopher Brown 2008-01-09 18:49:36 EST
The module gets loaded followed by:

tifm_sd: Unknown symbol mmc_request_done
tifm_sd: Unknown symbol mmc_remove_host
tifm_sd: Unknown symbol mmc_alloc_host
tifm_sd: Unknown symbol mmc_add_host
tifm_sd: Unknown symbol mmc_suspend_host
tifm_sd: Unknown symbol mmc_resume_host
tifm_sd: Unknown symbol mmc_free_host

I think your best bet is to test with 2.6.24 when that arrives (or as previously
indicated from rawhide) as a large number of fixes have entered the tree. If you
could do so and report back that would be appreciated.
Comment 14 Garry T. Williams 2008-01-19 16:22:41 EST
I know it's not 2.6.24, but I saw that updates-testing had and
installed it.  Still no joy.  I'll report when I have tested 2.6.24.
Comment 15 Garry T. Williams 2008-03-03 18:05:42 EST
I installed from updates-testing.

No joy.

Here's information from dmesg (this is FC8, yum upgraded from FC7):

tifm_core: MMC/SD card detected in socket 0:0
tifm_sd: Unknown symbol mmc_request_done
tifm_sd: Unknown symbol mmc_remove_host
tifm_sd: Unknown symbol mmc_alloc_host
tifm_sd: Unknown symbol mmc_add_host
tifm_sd: Unknown symbol mmc_suspend_host
tifm_sd: Unknown symbol mmc_resume_host
tifm_sd: Unknown symbol mmc_free_host

I mentioned before that I have no card in this slot.  I have never owned such a

To summarize, the effect of this bug is two-fold:

1.  On my laptop (Sony Vaio VGNFS640W), an LED lights up to indicate a card is

2.  Wake up from suspend to memory is accompanied by a "pop-up" message on the
KDE desktop that complains about not being able to remount the media (that I
never had mounted in the first place).

These symptoms are quite benign and are only a minor irritation.  I don't
anticipate ever purchasing an actual card for this slot, so I don't suppose that
I'll ever see any other symptoms.  Actually, I'll probably disable the loading
of that module and forget about this.  :-)

Unless you have any other diagnostics I could perform on this system, I suppose
you can close this bug as WONTFIX, CANTFIX, NOTABUG, ???.
