This laptop had no problems waking up using previous kernel releases, the latest I had tried before 2.6.27 being 2.6.18. After long trials, I traced the issue to the "processor.ko" kernel module: if I unload it - even while the screen is being crazy - all goes back to normal. Problem is, that module is needed to probe the CPU's temperature and - I think - for clock frequency stepping. Does anyone know how do I get to keep it *and* get working resume functionality? I'm using 32-bit Slackware 12.2 at the moment, but the exact same symptoms were shown by Fedora 11 x86_64. My laptop has an AMD Turion64 processor and an ATI Radeon Xpress1100 graphics card driven by X.Org's "ati" driver. Please write if you need lspci's output or more detailed info or tests. Thanks in advance for your comments. -- ~> cat /etc/*-{version,release}|head -n1 && uname -moprs|fold -sw72 Slackware 12.2.0 Linux 2.6.27.7-crrm i686 AMD Turion(tm) 64 Mobile Technology MK-36 GNU/Linux
