I'd appreciate any help on getting this report sent to the appropriate list and, of course, getting this fixed. I don't know what's useful, so you're getting everything. This will be a very long e-mail.My new laptop won't boot with kernel versions 2.6.21 or 2.6.22 . No oops. No panic. It just stops printing messages. Maybe it would eventually continue if I wait long enough, but it's unacceptable either way. I include below the contents of dmesg for a working kernel up to the point where it halts. I'm also including what it usually does for a few lines after that point. I did git-bisect on the 2.6.21.y tree. I'm including the result of that as well. It mentions HPET, so I should mention my computer also fails to boot when I enable HPET in my BIOS. I don't have the details of this currently; I can reproduce it again if needed. I've also included my kernel configuration and ver_linux output. You'll notice that my gcc version is 4.2.0, but this also happens with 4.1.2. I'm including /proc/cpuinfo and lspci -vvv. I'm including /proc/ioports and /proc/iomem. I don't have a /proc/scsi. Thanks, Mark Here's the commit that causes the problem: e9e2cdb412412326c4827fc78ba27f410d837e6e is first bad commit commit e9e2cdb412412326c4827fc78ba27f410d837e6e Author: Thomas Gleixner <[EMAIL PROTECTED]> Date: Fri Feb 16 01:28:04 2007 -0800 [PATCH] clockevents: i386 drivers Add clockevent drivers for i386: lapic (local) and PIT/HPET (global). Update the timer IRQ to call into the PIT/HPET driver's event handler and the lapic-timer IRQ to call into the lapic clockevent driver. The assignement of timer functionality is delegated to the core framework code and replaces the compile and runtime evalution in do_timer_interrupt_hook() Use the clockevents broadcast support and implement the lapic_broadcast function for ACPI. No changes to existing functionality.

As a wild guess, I'd bet that the rcu queues are failing to get called (probably some problem with the timer interrupt in the APs?), thus preventing the system to get into a quiescent state. It does seem timer related to me. Maybe one of the timer gurus have any other word on this? -- Glauber de Oliveira Costa.
