Did you do a hibernate and resume cycle before htting this error?
Yes.
We should probably turn off hibernation support since nobody seems to know what is causing the corruption.
That would mean no suspend support would be left at all.
I'm experiencing the same problem under VirtualBox with no suspend/resume or hibernation. at lib/list_debug.c:26 __list_add+0x54/0xb0() (Tainted: G W ---------------- ) Hardware name: VirtualBox list_add corruption. next->prev should be prev (c0a01048), but was edd61690.

these other reports aren't necessarily the same as the original bug reported. There are many linked lists in use in the kernel, and the debugging can be tripped up by many things. If you're still seeing them, please file separate bugs. Andreas, are you still seeing the original bug ?
