SD-Card slot empty but Kernel think it's attached

[Daniel Mehrmann]

Well, my Netbook has a normal harddisk and a SD-Card slot reader. My main disk runs fine:

[ 1.450126] ata1.00: ATA-8: SAMSUNG HM400LI, 2TF00_00, max UDMA7
[ 1.450160] ata1.00: 781422768 sectors, multi 16: LBA48 NCQ (depth 0/32)
[ 1.466126] ata1.00: configured for UDMA/133
[ 1.466581] scsi 0:0:0:0: Direct-Access ATA SAMSUNG HM400LI 2TF0 PQ: 0 ANSI: 5
[ 1.466990] sd 0:0:0:0: [sda] 781422768 512-byte logical blocks: (400 GB/372 GiB)
[ 1.467089] sd 0:0:0:0: Attached scsi generic sg0 type 0
[ 1.467252] sd 0:0:0:0: [sda] Write Protect is off
[ 1.467272] sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00
[ 1.467392] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
[ 1.503545] sda: sda1 sda2 sda3
[ 1.504727] sd 0:0:0:0: [sda] Attached SCSI disk

But my SD-Card reader slot is always empty and i never used a card before.
Every time my system starts the kernel found it and attach a device, which might
be wrong because its empty:

[ 7.870635] scsi 2:0:0:0: Direct-Access Generic- Multi-Card 1.00 PQ: 0 ANSI: 0 CCS
[ 7.873147] sd 2:0:0:0: Attached scsi generic sg1 type 0
[ 7.877771] sd 2:0:0:0: [sdb] Attached SCSI removable disk

Well, now the kernel tries to find out some technical data about the device which
doesn't work of course. So my kernel log get spamed time of time:

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.4kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Daniel Mehrmann (daniel-mehrmann)]

Ok, I'll do that on monday next week (07.05.2012), because i don't have my system at home right now.

[Daniel Mehrmann (daniel-mehrmann)]

I'm using this kernel right now:

daniel@Homer-Mobil:~$ uname -a
Linux Homer-Mobil 3.4.0-030400rc6-generic #201205061835 SMP Sun May 6 22:42:47 UTC 2012 i686 i686 i386 GNU/Linux

and the "bug" is still there :-(

I've attached new log - and install files.
I hope this might help you. :-)

[Daniel Mehrmann (daniel-mehrmann)]

Oops, i think my bugreport seems duplicate of 925760. Sorry for that.
