Hi: just a general pointer, this bug report would be a lot easier to read if you attached the big dmesg output as an attachment rather than in-line and only provided the relevant line from lspci (at least for me: I'm not sure what the kernel team or general launchpad etiquette is).
Regarding upstream development, what is "a long time" for inactivity? Things seem to have slown down a little bit since 2.6.17 (the first mainline kernel to have the driver integrated) but I don't think they have stopped. What is the capacity (i.e. 512MB, 1GB, etc.) of your working SD card and your non-working SD card? It's worth trying the vanilla 2.6.18 kernel as supplied by kernel.org. If the problem does not exist with that, then it's a matter of backporting the fix, I imagine. If the problem _does_ occur with 2.6.18, then the sdhci-devel people will be interested. -- Can't use some MMC cards https://launchpad.net/bugs/60618 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
