Description of problem: The system will hang while the kernel is initializing if the option acpi=off is not specified on the kernel command line. After the hang occurs, the Num Lock key on the keyboard no longer turns Num Lock on or off. This is an Acer Veriton 6900 Pro system, Intel Pentium D dual-core CPU, Phoenix-Award BIOS. Version-Release number of selected component (if applicable): Fedora release 6.92 (Rawhide) Linux localhost.localdomain 2.6.20-1.3023.fc7 #1 SMP Sun Mar 25 22:12:02 EDT 2007 i686 i686 i386 GNU/Linux How reproducible: Boot system without acpi=off option Actual results: System hangs Expected results: Booted up system Additional info (attachments): good.txt is a log of the kernel messages when the acpi=off option is specified. bad1.txt is a log of the kernel messages with no extra options bad2.txt is a log with acpi=ht acpi_dbg_layer=1 acpi_dbg_level=1 apic=debug debug pci=noacpi

Fedora 7 test bugs should be filed against "devel", not against test1/2/3. This isn't obvious, I know. Moving this report so it isn't lost. This is a bulk message -- I apologize if this was actually meant to be targeted against a different release. If so, please fix or let me know. Thanks.
The hang actually seems to be caused by MMCONFIG, and specifying pci=nommconf allows the kernel to boot and ACPI to be enabled. I am changing the summary and this is still present in Fredora 8 test 3; kernel 2.6.23-0.214.rc8.git2.fc8.
Please see http://bugzilla.kernel.org/show_bug.cgi?id=8308#c16 the patch referenced there resolves this problem.
Upstream has had that patch submitted but there were objections from some of the PCI developers.
Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.
This bug has been in NEEDINFO for more than 30 days since feedback was first requested. As a result we are closing it. If you can reproduce this bug in the future against a maintained Fedora version please feel free to reopen it against that version.
