I have a Laptop (F11Y) with a build in SD Card Reader, which works very well with current kernels. At the moment I analyse 2.6.28_rc7. After last update of my portage tree the util-linux-2.14.1 was merged. But with this version I have no longer SD/MMC Card access. fdisk -l don't show the card any longer. First I thought it must be a bug in current kernel, but also 2.6.27.7 and 2.6.26.2 don't show the card. After backward to util-liunx 2.13.1.1 the sd/mmc card was shown with fdisk -l. Reproducible: Always Steps to Reproduce: 1. build a current kernel >=2.6.26 with mmc/sd/sdio card support 2. insert a sd card in your card reader 3. fdisk -l should show the card as something like /dev/mmxblk0 Actual Results: With new util-linux-2.14.1 mmc block device will not shown.

run like `dd if=/dev/mmxblk0 of=foo count=100` and then run `fdisk -l foo` ... if that still works with util-linux-2.13.1 but fails with 2.14.1, compress the file and post it as an attachment
What I've done: dd if=/mnt/mmcblk0 of=foo_2.13.1.1.dat count=100 with util-linux-2.13.1.1 then rebuild util-linux-2.14.1, reboot, why: may be /dev will change. Then: dd if=/mnt/mmcblk0 of=foo_2.14.1.dat count=100 fdisk -l no longer shows the sd-card. I checked the difference of foo_2.13... and foo_2.14... in emacs with hexl-mode and ediff-buffers. There are no difference. I can mount the sd-card with util-linux-2.14.1: mount /dev/mmcblk0p1 /mnt/mmc -t vfat dmesg shows me the card. [...] mmc0: card 0001 removed mmc0: new SD card at address 314b mmcblk0: mmc0:314b SD01G 982 MiB mmcblk0: p1 mmc0: card 314b removed mmc0: new SD card at address 314b mmcblk0: mmc0:314b SD01G 982 MiB mmcblk0: p1 [...] I started /etc/init.d/hald and in /var/log/messages I can see an reaction after insert a sd-card.

I know this has nothing to do with the util-linux but with the kernel. Therefore it seems only fdisk has problems to see the card. All other seems to works as expected.
but you missed the important part of my comment: run fdisk on the *file*, not the device, and then compress the file and post it as an attachment.

post the full strace output as an attachment of `fdisk -l` on the real disk strace -s 4096 -f -o log fdisk -l ......
Created attachment 174659 [details] 4 straces of fdisk The tar.gz files contains 4 different straces. # fdisk of foo.dat strace -s ... fdisk -l foo.dat with 2.13.1.1 strace -s ... fdisk -l foo.dat with 2.14.1 # fdisk -l strace -s ... fdisk -l with 2.13.1.1 strace -s ... fdisk -l with 2.14.1 hope that helps.
