Dell Inspiron 5000: wakeup/resume fails after suspend

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0rc2) Gecko/20020510 Description of problem: After suspending the machine with Fn-ESC or closing lid and resuming the harddrive will not always wake up and the machine freezes. Sometimes the suspend itself already fails. Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1.Suspend the machine 2.Wakeup the machine 3.Reboot and watch fsck fixing the fs :-( Actual Results: Sometimes the machine freezes on wakeup and a hard reset is necessary. Expected Results: Machine should properly resume. Additional info: This appeared already in 7.2, but less frequently. 7.1 was MUCH stable, even though I sometimes saw this happening, too. I have found the following workaround for 7.3: put in /etc/sysconfig/apmd: PCMCIARESTART="no" PCMCIABIOSBUG="no" PCMCIAWAIT="no" RESTORESERVICES="network named pcmcia" My personal guess is the cardbus/PCMCIA controller is not properly woken up by the BIOS. Shutting down pcmcia completly before suspend and to a restart afterwards seems to work much better than the plain PCMCIARESTART using hotplug. My PCMCIA wireless network card even finds the network after resume now. With the PCMCIARESTART="yes" approach that does not happen (the card comes alive but it seems iwpriv is not called or called to late to set the password settings). I set the severity to high as I frequently lost data related to this instability.
I have a similar problem on my Compaq laptop. The sympthoms are slightly different, but the outcome is the same. The laptop regularly freezes coming out out suspend. This goes in stages. First the terminal screens start to show all sorts of coloured rectangles, but X-windows remains functioning. On a next suspend, X-windows starts the "shake". If I'm quick enough I can still manage to do a Ctrl-Alt-Del, but otherwise: freeze. I'll look at the suggestions made about PCMCIA as I also have a modem in the machine. I never had this problem before with RedHat 7.2, hence the culprits my be: 1) New kernel 4.2.18 (yet it also happens with the old kernel 4.2.9) 2) New XFree86 4.2.0 instead of 4.1.0 3) New hotplug
Would you provide the BIOS version Axx that you have? I suppose it's the latest and greatest for support.dell.com. If not, I just wanted to let you know that Dell keeps fixing the suspend resume problem over the time on this laptop and the others, and you should update it too.
I am using the latest A08 BIOS. With the workaround described above the notebook surives 3 out of 4 resumes, but is still freezing from time to time. Be advised: The A08 BIOS has a severe bug with the PS/2 keyboard/mouse, causing the keyboard to freeze if the PS/2 mouse is not polled (external USB mouse). I have reported this bug and a workaround separately.
I am having a similar problem with my IBM ThinkPad A20m. I used to be able to come back from suspend with rh71 so long as I was on a console, and my drive would eventually spin up and things would resume, but now on wake up my drive does not spin up. In console mode, characters won't echo back, but the system acknowledges me toggling CapsLock. In X, apps will seem to resume for a few seconds then lock up (Ctrl-Alt-Backspace doesn't get me out of X).
I have a similar problem with my Dell Inspiron 5000e. The latest BIOS I can find for mine is A06 (which I have). If I eject the PCMCIA network card, suspend/resume works OK (so far). I then plug in the network card, run /etc/init.d/network restart (as root) and everything works. Not a very "clean" work around, but one that keeps me up and running. I did find one other web page that suggested using the pcmcia-cs package from version 7.0 (it needs to be recompiled every time you upgrade the kernel), I haven't tried that. Instead I tried upgraded to the newest version of pcmcia-cs (from RH8.0) - sorry to say, it didn't fix the problem. I'll keep posting to this bug and #41390 with any results I find.
Closing out bugs on older unsupported releases. Apologies for any lack of response. Please reopen if it persists on current releases such as Fedora Core 3.
