To recreate: Suspend (using the suspend key, by closing the top, or using the apm command), then hit the power button for resume. When the system wakes up some IDE I/O occurs (with flashing disk light and audible head motion), then the disk light comes on and stays on. Switching consoles is possible, and typed characters echo, but no commands run. The system can be powered down by holding the power button down for 10 seconds, but that's about it. The system seems stable otherwise. It stayed up all last weekend, for example. If you wait in the locked state long enough, the 2.4.14 and 2.4.18 kernels usually (but not always) output the following to the console: hda: timeout waiting for DMA ide_dmaproc: chipset supported ide_dma_timeout func only: 14 Kernel versions I've tried this on: 2.4.14, 2.4.18 (vanilla), 2.4.18-3 (RedHat), 2.4.19-rc1, 2.4.19-rc1-ac5 4-year old stuff on http://www.pihl.org/linux/linux-dell.html associates a similar problem with pcmcia being active; however I get the same symptoms without loading any pcmcia related modules. I can provide more details to interested parties; willing to apply/try patches.
