I have tried to narrow down the problem further. This is quite time consuming as sometimes the crash does not occur in 20 suspend and resume cycles and next time it crashes after the second try. Anyway, resume works reliably when booting with init=/bin/bash. It also works reliably if I switch to a text console and kill gdm leaving the nvidia module loaded. However, using both methods the screen stays black after resuming but the keyboard works. There were also no crashes so far using the vesa driver instead of the proprietary NVIDIA driver. I tried all combinations of the options in the acpi-support file but it did not work reliably with the proprietary NVIDIA driver. The kernel parameter acpi_sleep=s3_mode did not help too. Nevertheless, the problem seams to be caused by the proprietary NVIDIA driver or the interaction of the kernel and this driver. Is there any way to remove this driver before suspending? Using the vesa driver is not a real alternative as it does not provide 3D acceleration and consumes much more energy from battery.
