Description of problem: During a fresh install of FC7 on an Acer Travelmate 803LMi I experienced random hangs during the installation, sometimes before the first screen asking to check the media, sometimes later. Installing in text mode does not help. Adding the kernel options "acpi=off noapic" does help. With these options I could install the system. After booting the installed system with the default kernel command line, I experienced again random hangs during the boot process. Sometimes I got a stack dump listing quite a few function names starting with acpi (I will write them down next time I see them). Often the system simply hangs. Adding acpi=off to the kernel command line gives me a bootable system. I can even hibernate the system and resume (only tried once), but not in a useful fashion: without acpi the laptop does not power off properly, so I have to press the power button. Upgrading to kernel 2.6.21-1.3228 does not help. Version-Release number of selected component (if applicable): FC7 How reproducible: Always Steps to Reproduce: 1. Boot installation cd 2. Try to install 3. Install hangs Actual results: System hang. Keyboard and mouse do not work. Changing consoles does not work. Expected results: Well, you can guess.. Additional info:

242369 could indeed be the same bug. It could also be related to the following kernel bug: The problem may be related to this bug: http://bugzilla.kernel.org/show_bug.cgi?id=8385 I think the title of 247721 is a better description than the title of 242369. *** This bug has been marked as a duplicate of 242369 ***
