It seems i can boot on 2.6.14 kernel when i reboot from Win2K or from 2.6.13 kernel.

Same happens to me, but with a D600 instead, almost the same harware.
I have seen it mostly on 2.6.14_1.1656, but also with 1653. Anyway it happens
almost always, but sometimes it works. 

I have another D600 with 1653 that has never seen the bug. But on a new one,
fresh FC4 install and yum update -> BUG. 

Exchanging the hard disks of the two laptops moves the bug to the other computer.

The is what I see from a serial console:

Red Hat nash version 4.2.15 starting
INIT: version 2.85 booting
                Welcome to Fedora Core
                Press 'I' to enter interactive startup.
Iniciando udev:  [  OK  ]

BUG: spinlock lockup on CPU#0, events/0/3, c1a07114 (Not tainted)

I have also tested with a plain vanilla 2.6.14.6 and the same thing happens.


Comment 3 Dave Jones 2006-02-03 06:15:31 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.

This bug has been placed in NEEDINFO_REPORTER state.
Due to the large volume of inactive bugs in bugzilla, if this bug is
still in this state in two weeks time, it will be closed.

Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.

If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.

Thank you.
