Description of problem:
With severn CD 1 in the CD driver of my HP Pavilion ze5250 laptop computer, I
boot (or do power-on) and things proceed normally until
the first install window (the one that allows me to test my CDs).
At that time the keyboard and everything else freezes. Ctrl-Alt-Delete does not
work. I must power-on. At power-on, under the same circumstances, the same
To fix: about midway through the bringup sequence, during initscript
processing, I press and hold the ENTER key (thus causing many keyboard
interrupts per second). I keep the key held. This always results in the CD1
test beginning, at which time I release the ENTER key. Tests of CD2 and CD3
proceed normally. Installation proceeds normally.
This problem, and its fix, occur 100% repeatably.
I had the same problem installing RedHat 9, shrike, on the same laptop a few
months ago, and I resolved it the same way, by pressing and holding the ENTER key.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.put severn CD1 in CD drive
3.wait for CD verification window
4.attempt to hit ENTER
Actual Results: nothing
Expected Results: CD1 testing should have started
Does booting with 'acpi=off' help?
No, acpi=off does not change the symptom.
I booted with severn CD1 in the CD drive. At the boot: prompt I typed
and hit enter. Booting began. At installation setup I received a box
saying that ohci1394 was loaded. The next box was for CD testing, and
the keyboard was unresponsive. I could not do Ctrl-Alt-Del. I had to
power-off in order to recover the computer. The symptoms are the same
as before, when I did not use acpi=off.
I had installed severn by the workaround described in my original report,
above; it still works fine. This additional note is in (belated; sorry)
response to Jeremy Katz's question. Happy to try further suggestions.
Happy to test boot floppy images or other workarounds you may want me
I have a HP Pavilion ze4540 while trying to install Fedora Core 1 I
faced the same problem.
The solution I came up with it to disable Legacy USB Support in the
BIOS. So far everything else seems to be working fine (even the
Microsoft USB Scroll Mouse).
Hope it helps,
