WARNING: at /build/buildd/linux-2.6.28/kernel/power/main.c:177 suspend_test_finish+0x7c/0x80()

[Per Ångström]

Shortly after the KernelOops was detected and reported by the applet, my machine hung and would not react to Alt+SysReq magic.

Title: WARNING: at /build/buildd/linux-2.6.28/kernel/power/main.c:177 suspend_test_finish+0x7c/0x80()

[Tormod Volden (tormodvolden)]

The warning is sometimes harmless, but can indicate something is resuming too slowly. It can be a problem in the nvidia kernel module. Can you please attach the full log with the warning?

[Per Ångström (autark)]

I'm not sure which log you want, so I'm trying with the syslog.

[Tormod Volden (tormodvolden)]

So the warning is just the > 5s resume. The hang must be something else. Does the hang happen often?

[Per Ångström (autark)]

No, that was the first time in a while. I used to have similar trouble all the time with the free nvidia driver resuming from suspend and hibernation, but that went away when I switched to the proprietary driver.

Hi Guys,

I'd consider the warning to be a duplicate of bug 287453.

As Tormod mentioned it's just a warning. The issue of the machine hanging is likely a separate issue. You mentioned the hang doesn't happen often and thus not highly reproducible. Let continue to monitor this into the Karmic development cycle.
