Comment 7 for bug 362920

I ran into this Suspend bug on a D600 with Karmic as well (2.6.31-14-generic #48 i686) and was able to identify the culprit as the yenta-socket module (for PCMCIA). I found the culprit by using the pm_trace as suggested at https://wiki.ubuntu.com/DebuggingKernelSuspend (the PCI address came up which I mapped with lspci -v). When I blacklisted yenta-socket, rsrc-nonstatic, and pcmcia-core, I rebooted the machine and suspend now works.

This is my brother's D600, and I will only have access to this machine for the next couple days before my brother heads back to CalTech, so if you need any more info, let me know asap (I normally run Gentoo on a Lenovo T400).
