-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The following is the text from my e-mail that i have posted yesterday regarding the similar issue. My laptop is equipped with AMD Dual Core processor X2. Thought it might be relevant. - ---------------------------------------------------------------------------------------------------------------- I grabbed the following from dmesg when i tried to "suspend" the laptop. After booting the laptop, the first suspend was successful. The error occurs during the second "suspend". System did not crash though, i mean it was still functional except that the PM (power manager) throws a pop up saying that the suspend was failed.
