Since a week or so I had problems with my Nikon D100 camera reading my CompactFlash cards. On my 'normal' PC this ended up in errors, and yesterday I updated my iBook and have the same errors (while my PC was broken, my iBook still worked). Jul 15 22:20:36 iBook end_request: I/O error, dev sda, sector 2000880 Jul 15 22:20:36 iBook Buffer I/O error on device sda, logical block 2000880 Now It is very interesting, because the device itself has 2000881 sectors. It ends up in an error also described here: http://bugs.gentoo.org/show_bug.cgi?id=84725#c14 Interesting enough... "can't read superblock", is the error. But there is *no* data comming from this device, even with a dd noerror command. I verified it isn't the cable or device. My neighbor is able to read the camera and Compact Flash card with Vista, and the camera doesn't complain about reading the card. I know it is not glibc related, but suspect it has a background in udev. I have tested a normal USB1 memorystick, which *still* works as expected. Reproducible: Always Steps to Reproduce: 1. plugin in camera Nikon D100 2. /dev/sda and /dev/sda1 are made 3. mount /dev/sda1 /mnt/floppy -t vfat 4. can't read superblock Actual Results: 4. can't read superblock Expected Results: A normal mount like usbstick.
emerge --info please.
Created attachment 125027 [details] Update session (changes) I currently don't have a portage tree here (holidays), but i'll create it, if the WiFi link is stable enough :) To provide some information: Kernel: 2.6.21-gentoo-r4 Use flags: */* dbus -ruby -gpm -bonobo -mikmod -kde -esd -arts -qt -qt3 -qt4 startup-notification msn dvi t1lib pdf cairo -qt -qt3 -qt4 -cups -gnome -eds v4l -postgres -ldap sqlite ilbc tetex opengl sdl xml xsl -odbc tcltk ffmpeg spell X nsplugin jpeg tiff gtk gtk2 nptl nptlonly userlocales pic altivec bzip2 nls -berkdb alsa mmap ogg flac speex dv encode vorbis ieee1394 network theora gsm mp3 fbcon lcms glitz curl png xprint xfs mad xv udev gps mozbranding -gimp -exif hal -gstreamer -doc libnotify sqlite3 -gdbm And you can find the update session in the attached file. So the ones that jump into my eyes are the HAL update and the udev update. The kernel wasn't updated. Maybe it could be fixed in 2.6.22 (but this wasn't in ~ppc yet).

I got a reply from Alan on my question if anything was changed in the vanilla-kernel lately, and it wasn't. So an option question stays: is something changed in gentoo-sources that might have caused this camera to stop functioning? Or should this search be narrowed to the updated userland packages?
Gentoo's patches are very light, we don't change anything in this area and haven't done in a long while. Please keep us updated on the fate of the patch...

Please keep us updated on the fate of the > patch... > Fate: This patch (as938) adds an unusual_devs entry for the Nikon DSC D100. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> But you must agree it is strange that two systems stop working after upgrading? Currently I'm holiday, but I have at home at least one machine that is still running on an old kernel and basesystem. So it my be interesting to find out what in userspace is the cause for this. Since I was running 2.6.21 from April, I'm pretty sure that it is the only component that was not changed. (thanks to /var/log/messages)
The quirk added indicates that the device reports an off-by-one capacity. You will not see any problems until something tries to access the last sector on the disk, and at that point, everything else will screw up. So, it's not unreasonable to think that previously, nothing was trying to access that sector, but now something is. Reopening the bug so that we can track the patch and include it in gentoo-sources.
This is a note to let you know that I've just added the patch titled Subject: USB: usb-storage: unusual_devs entry for Nikon D100 to my gregkh-2.6 tree. Its filename is usb-usb-storage-unusual_devs-entry-for-nikon-d100.patch This tree can be found at http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/patches/
Thanks for the update, will include in future releases
Fixed in gentoo-sources-2.6.22-r2 (genpatches-2.6.22-3)
