Hello. I have a Dell 600m x86 laptop here and I am using suspend-to-ram ("suspend"). With kernel 2.6.11, everything works fine for months at a time- the machine suspends, resumes, there is no problem. However, kernels 2.6.12, 2.6.13, and 2.6.14 have all exhibited the following problem: every few days the machine will not resume. I open the lid, it powers up, hard drive light flashes once or twice, and nothing else happens. The screen backlight will not even come back on. I have to power the machine off manually and boot it up again, losing everything that was open when the machine suspended. This is not an issue with other software on the system. After 2.6.12 refused to resume, I went back to 2.6.11 and everything worked fine again. When 2.6.13 came out, I built that and again, sometimes it will not resume. I went back to 2.6.11 again and everything worked fine again up until I switched to 2.6.14. It worked fine for two days, and now it too locked up during resume. I don't want to be stuck on kernel 2.6.11-gentoo-r6 til the end of time. There must have been some significant changes between 2.6.11-gentoo-r6 and 2.6.12 (both gentoo and vanilla versions) that introduced this... Does anyone have any ideas? Here is a link to my .config for 2.6.14 if anyone wants to look at it: http://wam.umd.edu/~stevenm/config2614 Thanks for the help -- Steve Reproducible: Sometimes Steps to Reproduce: 1. Suspend laptop 2. Wait 3. Resume Laptop 4. If resumes, wait a few days, goto 1 5. If locks up, then you have a problem
Gentoo's patchset is minimal and we haven't been including patches that would affect suspending at this level. Please file this as an upstream bug at http://bugzilla.kernel.org and post the new URL here.
