Comments, Suggestions & Questions / Re: New kernel
« on: 2008.12.18, 14:23:08 »Hi Pete,
Hi djcaetano
You state earlier in this thread "Also, no changes on using SMP and OS/4 Kernel: enabling SMP
detection on ACPI caused the system to freeze when starting to process the RUN statements of CONFIG.SYS."
Just to clear my statement, using SMP with IBM's SMP kernel sometimes causes a freeze.
Using SMP with OS/4 SMP kernel always causes a freeze.
Can I ask what switches were in use on the PSD= line? and also what mainboard chipset is involved?
No problem. My PSD line is:
PSD=ACPI.PSD /SMP /APIC
I had tested other parameters some months ago, but no luck. Any suggestions?
The chipset is Intel G31 Express (north bridge) and Intel ICH7 (south bridge).
Might also be worth checking exactly where the system gets stuck... do you have an empty text file called ALTF2ON.$$$ in the root directory of your boot drive? If not create 1 with a text editor - simply save an empty file to that drive:\path\filename - and see if that helps identify where the boot stops.
Well, in fact I had already did this test. It freezes always in the moment it will execute the first RUN statement. I had already tried to change the order of previous statements and it freezes in the same place (on the first RUN statement). I modified the order of RUN lines on config.sys and the boot keeps freezing on the first RUN statement.
I seems a problem related to the way RUN statement is processed by the kernel. Weird, huh?
I'll do some more tests later. With OS/4 kernel it is easier to test, since it always hangs in that
place.
I also note that you are using ACPI v3.11 - might be worth updating that to v3.14 (the latest, v3.7 is awhile away I think :-)
Yes, I have to renew the eCS "software subscription".
Anyway, this boot-freeze problem is being a constant since earlier versions of ACPI, never changed a bit. And the freeze only happens when using SMP kernel. With UNI kernel the boot is always flawlessly completed.
As soon as possible (probably next month) I will renew my subscription and test the new ACPI version.
