Distribution: Fedora Core 2 Hardware Environment: Dell Inspiron 8500 Software Environment: gcc 3.3.3 Problem Description: Resuming from suspend (s1 or s3) results in the system freezing. The last output i see is this; PM: Finishing up. ACPI: PCI interrupt 0000:00:1d.0[A] -> GSI 11 (level, low) -> IRQ 11 PCI:: Setting letency timer of device 0000:00:1d.0 to 64 ACPI: PCI interrupt 0000:00:1d.1[B] -> GSI 11 (level, low) -> IRQ 11 PCI:: Setting letency timer of device 0000:00:1d.1 to 64 ACPI: PCI interrupt 0000:00:1d.2[C] -> GSI 11 (level, low) -> IRQ 11 PCI:: Setting letency timer of device 0000:00:1d.2 to 64 To enter suspend, i boot into runlevel 3, and remove ehci_hcd and uhci_hcd modules and disable and remove networking modules and services. then enter suspend using echo "1" > /proc/acpi/sleep Suspend works fine, however on resume it hangs. I have tried the kernels that are supplied with fedora, and I have tried running kernel 2.6.7 + the 20040715-2.6.7 acpi patch with no sucess. S1 did used to work when running the 2.4 kernels from fedora core 1. Steps to reproduce: 1) Boot into run level 3 (without framebuffer mode) 2) remove uhci_hcd and ehci_hcd modules 3) disable network services 4) remove network modules 5) echo "1" > /proc/acpi/sleep 6) Press power button to resume. then System freeze

Latest BIOS on this system? same result with linux-2.6.9 + acpi patch?
Running with bios A06 and kernel 2.6.9 + acpi_patch fixes the problem with S1 freezing. I can now suspend and resume ok. S3 now also resumes, however the display stays off. However i can log in remotely. Trying different acpi_sleep options resulted in the system rebooting on resume.
Can you also - Try the workaround in bug #3670 And try not using X or the framebuffer. Use VGAtext console (deCONFIGure framebuffer in your kernel).
I had already tried the console w/out framebuffer with no luck. The video_post program now turns the display back on. It now seems that something breaks X; it runs at 99.9% cpu usage and fails to display. No console terminals are available either. Remote logging in to kill -9 X fixes this. video_post in just the console seems ok.
OK Then. This bug can be marked duplicate of #3670. Please look at the latest comment on bug #3670. That should help you get the X working after resume.
