Description Patrick Steiner 2007-06-06 05:42:33 UTC

Description of problem:

I have updated my Dell D420 Laptop via yum from FC6 to F7. 

But after a reboot the Laptop hangs directly after grub. Only some kernel
messages where shown. no sysinit. but i cant read any error.

any ideas how i can see a better debugging?


Version-Release number of selected component (if applicable):
Fedora 7 
Kernel 2.6.21-1.3194.fc7

Comment 1 Patrick Steiner 2007-06-06 05:53:27 UTC

i found a workaround. set acpi=off as bootparameter and the kernel boots.

is there a acpi problem in 2.6.21 ?

Comment 2 Hans de Goede 2007-06-06 15:00:17 UTC

This is a known problem with Dell Duo Core laptops. The usual workaround is to
boot with a maxcpus=1 option. A better workaround could be to use the
clocksource=acpi_pm option, that seems todo the trick for most users as
discussed in bug 241249, of which this is a duplicate.

Closing as a dup of bug 241249.
