log file with the errors
I updated the RHEL 4 from update 2 to update 4 (including kernel). By the reboot
the problem begins. In the messages file say disable acpi (acpi=off). The
problem is gone.
What does acpi?
ACPI stands for Advanced Configuration and Power Interface and basically handles
the how the machine is configured (hardware wise) and used mainly for power
management while it is running.
Some systems have broken or bogous ACPI implementations and so might requires
the acpi=off flag during bootup to work properly.
This is a kernel bug though, so i'm reassigning it to kernel component.
Read ya, Phil
Gerard, could you boot with "noacpi" and let me know if your system boots?
I shall try, is "noacpi" not the same as "acpi=off"?
Hi Gerard, whoops -- I didn't read comment #2 carefully enough. Thanks.
Could you send me details on the system you're using? Who the vendor is, output
from /proc/cpuinfo, etc.?
The vendor is a HP DX2000. I did a sysreport and upload this file.
