Description of problem: Boot process intermittently stops and locks up. This happens on about 1 in 5 boots. When it does not happen, the boot proceeds to the login prompt. When it does happen, it always happens in the same area of the boot messages, around this snippet cut from dmseg (one of these lines are the last displayed): ACPI: PCI Root Bridge [PCI0] (0000:00) PCI: Probing PCI hardware (bus 00) PM: Adding info for No Bus:pci0000:00 Boot video device is 0000:00:05.0 0000:00:0d.0: cannot adjust BAR0 (not I/O) The notebook must be manually turned off at this point. I have tried various boot options such as acpi=off, nosmp, and noapic; but no combination seems to totally fix the problem. The problem occurs slightly less often with this kernel and happened much more often with the original kernel on the Fedora 7 Test 3 Live CD. This is on an HP dv6000z notebook with dual boot Windows Vista It has a Phoenix BIOS with latest firmware to date; version F28 AMD Turion(TM) 64 X2 Dual-Core TL-56(1.8GHz/1MB) NVIDIA(R) GeForce(R) Go 6150 Video Kernel: Linux version 2.6.20-1.3040.fc7 Steps to Reproduce: 1. turn on notebook. 2. fiddle with boot options at grub stage, if desired. 3. watch for above pasted boot messages Actual results: when it gets to above pasted boot messages, boot stops on about 1 in 5 tries. Expected results: boot continues to login prompt. Additional info: Once (if) the boot process gets by the troublesome point, there doesnt seem to be any ill effects there after.

Updated latest Fedora 7 changes as of 04/06/2007, which includes kernel 2.6.20-1.3045.fc7 and same problem persists. With these updates, an additional problem has been introduced in that even when the early boot process proceeds forward with no crash, now it crashes when X starts up; every time. Cannot boot directly into runlevel 5, nor runlevel 3 then startx. Same result- blank screen and no response. Going back to kernel 4050, used for this post.
Bulk message: Fedora 7 test bugs should be filed against "devel", not against test1/2/3. This isn't obvious, I know. Moving this report so it isn't lost.
Installed 3053 and then 3054 kernel and still crashing on boot at same area as described above. These 2 kernels also cause X to crash everytime. Now using kernel 3054 (Linux version 2.6.20-1.3054.fc7 (brewbuilder.redhat.com) (gcc version 4.1.2 20070403 (Red Hat 4.1.2-8)) #1 SMP Mon Apr 9 15:25:58 EDT 2007) and after fiddling around with boot options; added noapic irqpoll and boots ok most of the time; x starts up, and usb devices work ok. Even with these boot options, the intermittent boot halt STILL occurs at the boot area as described above.
This is nolonger occurring with the latest test 4+ kernel: Linux version 2.6.21-1.3116.fc7 Seems to be fixed.
