Public bug reported:
The Live CD of Ubuntu 8.10 'Intrepid Ibex' Release Candidate hangs
during boot on my Compaq Presario F700 laptop. I am using the RC version
for AMD64 on a Compaq Presario f750us laptop. It has the linux kernel
version 2.6.27-7.13.
When I press the power button, it starts up, and begins booting from the
CD. I choose English as my language. I press 'Enter' to boot without
changing my computer. The splash screen appears, with the progress bar
scrolling back and forth. Soon, the progress bar stops scrolling, and
nothing else happens until I press the power button TWICE. Then it
resumes booting up as if nothing were wrong. It boots up fine, with no
apparent after-effects.
Shutting down the computer works as expected, pausing to eject the CD,
and resuming shut-down after I press 'Enter'. Also, if I press 'Ctrl'
instead of the power button, at the point where it hangs on boot, the
progress bar will resume scrolling as long as I continue to hold down
the 'Ctrl' button, or if I intermittently press it, until boot-up is
complete. This causes the laptop to boot considerably more slowly than
pressing the power button at the point of hang.
Booting without the splash screen, the last line that appears before it
hangs is:
[ 2.874771] ehci_hcd 0000:00:04.1: irq 22, io mem 0xf6489400
I press the power button, and it hangs immediately again, after posting
only this line:
173.615792 Clocksource tsc unstable (delta = 4398046091428 ns)
When I press the power button again, the boot-up process continues to
completion. I have a usb mouse that I use with my laptop. All of the
above was with the mouse plugged in to a usb port. When I start the
laptop without the mouse plugged in, the above is the same, except that
it doesn't hang at the line about ehci_hcd. Instead, it hangs at this
line:
[ 2.769120] forcedeth 000:00:0a.0: PCI INT A -> Link[LMAC] -> GSI 20
(level, low) -> IRQ 20
Then immediately again at:
173.615792 Clocksource tsc unstable (delta = 4398046091428 ns)
