LinuxQuestions.org - various SD cards & file systems won't read (64bit Slack 14.0, kernel 3.6.7)

Same problem here (64bit Slack 14.0, kernel 3.6.7) with various cards & file systems, all of which work under other OSs & previous 13.37ish Slack setup. Device is Ricoh 823 rev. 07.

dmesg output:

Hmm... I tried the stock 3.2.29 Slack kernel & whaddyaknow, sd suddenly cards work. Whatever the problem is, it's not with Slackware.

I'm using the (newish) Ricoh e823 pci card reader. SDHC & SDXC cards work fine when i boot into Windows 7, and they also worked with my 13.37ish setup. They'll also work fine with the stock 14.0 kernel.

3.6.x hasn't done anything for me. No SD* card is recognised. The system doesn't see the insertions & ejections, and there's that message about voltages [see my dmesg output above].

There are ubuntu bug reports about this problem from about a year ago. I tried the setpci fixes mentioned on those threads without any luck.
