Description of problem: After updating the kernel to 2.6.18-1.2849.fc6 I'm unable to boot my system because the booting progress hangs after uncompressing linux. Version-Release number of selected component (if applicable): 2.6.18-1.2849.fc6 How reproducible: allways Steps to Reproduce: 1. Boot the system on kernel 2.6.18-1.2849.fc6 Actual results: The booting progress hangs after uncompressing linux Expected results: The system should boot without hanging
What was the last kernel release that booted correctly? Could you boot with initcall_debug and take a digital photo of the screen?
I have the same problem. The last working kernel was the one shipped with FC6 (2789 AFAIR). The latest update feezes when loading standard kernel, xen + kernel-xen seem to work fine. Here I type what I see on the screen: Calling initcall 0xc076b254: pcibios_assign_resources+0x0/0x81() PCI: Bridge: 0000:00:01.0 IO window: disabled. MEM window: f8000000-f9ffffff PREFETCH window: f0000000-f7777777 PCI: Bridge: 0000:00:03.0 IO window: a000-afff. MEM window: fc000000-fc0fffff PREFETCH window: disabled.

I have this too on a VIA EPIA EN-1500 with C7 cpu. both with kernel-2.6.18-1.2835.fc6 and kernel-2.6.18-1.2849.fc6 Last signs of life are idential in both cases: PCI: Bridge: 0000:00:01.0 IO window: b000-bfff MEM window: fb000000-fcffffff PREFETCH windw: f4000000-f7ffffff NET: Registered protocol family 2
I'm sorry but how do I boot my kernel with initcall_debug? On my system the last working kernel was the one shipped with FC6 (2789).
It is a bootup option, so in grub you hit 'e' on the kernel you have, scroll to the line that says 'kernel (hdX,X)/boot/vmlinz...' and hit 'e' again. Append to the end initcall_debug, hit Enter and hit the letter 'b'. That should do it.

The last line printed on the screen is: Calling initcall 0xc0764cd9:acpi_init+0x0/0x1fs2()
Bert, Tomasz, You have a different bug from Heiko. Your bug is bug 215154.
Created attachment 141693 [details] Output from dmesg with kernel 2.6.18-1.2798 which works fine.
I have a Asus P2B-DS motherboard with dual 500 MHz Pentium III CPUs upgraded from FC5 (initially FC4) to FC6. The stock FC6 kernel kernel-2.6.18-1.2798.fc6 works fine but the first update kernel kernel-2.6.18-1.2849.fc6 hangs on my machine, exactly as described above. Here is the output from dmesg taken with the default kernel kernel-2.6.18-1.2798.fc6
I hooked up a serial console to capture the output before the machine hangs using kernel kernel-2.6.18-1.2849.fc6 The ouput is shown in the next attachment. In the output you can find this line "IO/L-APIC disabled because your old system seems to be old overwrite with "apic" I added APIC as a kernel parameter and with this option the machine does not hang using the update kernel, as shown in the last attachment. The question remains what has caused this regression in the first place and how it can be fixed without this kernel option workaround?

Created attachment 141695 [details] Boot output from kernel 2.6.18-1.2849 with APIC option. Does not hang.

One of my test boxes also has a P2B-DS motherboard, and exhibits the same behavior...
I'm thinking that bug 215154 might be related after all. There was a bugfix for race conditions in init_call applied to the upstream kernel. It would be cool if someone could try it out. (I don't have the bug on my hardware). http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=735a7ffb739b6efeaeb1e720306ba308eaaeb20e

Reasonably certain this is indeed a duplicate of bug 215154 and closing accordingly. Discussing/investigating fixes. Anyone afflicted, please try booting with the 'apic' option, and if that gets you up and running, attach the output from 'dmidecode' to bug 215154. *** This bug has been marked as a duplicate of 215154 ***
