I have the same problem (Dell 530s with ATI HD2400XT video, with ati/radeon open source drivers). Going through the DebuggingKernelSuspend procedure I end up with
[ 1.765524] Magic number: 0:953:349 [ 1.765527] hash matches /build/buildd/linux-2.6.27/drivers/base/power/main.c:390 No further hash lines. On the odd occasion that my screen _does_ come back, I notice a whole series of error messages related to the ata subsystem. I haven't been able to capture them yet (they end with 'ata.1 {DRDY ERR}' type line but that doesn't say much). -- Resume doesn't work on a Dell 530s https://bugs.launchpad.net/bugs/313647 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
