Description jon martin solaas 2005-10-23 01:21:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
HW: Dell Inspiron 5150 P4 Hyperthreading. The kernel hangs after the printout of "isapnp: No Plug&Play devices found". Occurs on kernel-2.6.13-1.1526smp i686, kernel-2.6.13-1.1532smp i686. All previous kernel versions for FC4 has worked flawlessly. I have nvidia and ndiswrapper modules from rpm.livna.org installed, but this happens without those installed as well.

Version-Release number of selected component (if applicable):
kernel-2.6.13-1.1526smp, kernel-2.6.13-1.1532smp

How reproducible:

Steps to Reproduce:
1. Turn Computer on
2. Select a 2.6.13-kernel in grub
3. Let the machine boot

Actual Results:  boot process hangs after printout of "isapnp: No Plug&Play devices found".

Expected Results:  continue boot process, probably with printout of "Real Time Clock Driver 1.12", which is what happens when running 2.6.12 kernel.

Additional info:

The kernels are installed using yum update, grub.conf is updated automatically and is not customized in any way. No kernel parameter tuning or anything, just plain installation and configuration.

Confirmed as a problem on my machines (Fujitsu-Siemens, Silicon Integrated
Systems [SiS] 661FX/M661FX/M661MX Host, P4-2.8 HT). 

Same workaround possible as on #160358 (-> booting with acpi=off). Single
processor kernel boots on affected machines without any problem.

Comment 2 jon martin solaas 2005-10-27 19:24:40 UTC
acpi=off actually boots, but system hangs when loading ndiswrapper from livna
(ndiswrapper 1.4, and kernel module for latest 2.6.13 kernel)

Comment 3 Dave Jones 2005-11-10 19:10:33 UTC
2.6.14-1.1637_FC4 has been released as an update for FC4.
Please retest with this update, as a large amount of code has been changed in
this release, which may have fixed your problem.

Thank you.

Comment 4 Thomas Tendl 2005-11-11 07:22:11 UTC
same behaviour as before. smp kernel only boots with acpi=off

Comment 5 Dave Jones 2006-02-03 06:34:18 UTC
This is a mass-update to all currently open kernel bugs.

A new kernel update has been released (Version: 2.6.15-1.1830_FC4)
based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
