I searched a bit and followed the guide in https://wiki.ubuntu.com/DebuggingKernelSuspend
I captured the dmesg output and got 2 lines similar to the Wiki page: [ 1.814882] ACPI: (supports S0 S3 S4 S5) [ 1.815497] Magic number: 15:874:554 [ 1.815649] hash matches device ptya0 The Wiki page says that the only solution is to remove the module, but I am not sure how to do this with ptya0, which is not a module but a pseudo-tty ? Hope this is useful.
