Comment 1 Bill Nottingham 2001-02-17 22:18:36 EST
Congratulations, your bios doesn't like the kernel.
Comment 2 Arjan van de Ven 2001-02-19 07:26:48 EST
Try "apm=realmode" on the lilo "append" line, or on the lilo commandline
Comment 3 Ben Levenson 2001-02-20 16:54:47 EST
"linux apm=realmode" seemed to work OK.
FWIW, I wasn't able to reproduce the oops
when I booted with linux-up.
Comment 4 Arjan van de Ven 2001-02-21 03:31:21 EST
Were you using the apm=power-off option ?
Comment 5 Glen Foster 2001-02-21 10:08:57 EST
This defect is considered MUST-FIX for Florence Gold release
Comment 6 Ben Levenson 2001-02-21 19:58:14 EST
no. the system is running with a default lilo.conf file.
I just tried passing the apm=power-off option, and
I didn't get an oops.
Here are all of my results:
linux-up --> no problems
linux apm=realmode --> no problems
linux apm=power-off --> no problems
linux --> oops
I just realized that some of the Call Trace was not included
in my original posting.  Let me know if you need me to
attach another copy.
Comment 7 Arjan van de Ven 2001-02-22 03:53:05 EST
No need for the call-trace, it's the bios that faults. You seem to be the
(un)lucky owner of a machine with a crappy bios. We can revert back to 
beta3 behavior, but that breaks for a hole lot of other people. The basic
dilemma was

<it doesn't work for a lot of people> vs <it oopses for a few, but we can give
                                          them the commandline option>

Now, it woud be nice if we could make this PCI id dependend, so please post 
lspci and lspci -n here. (and also the brand of the motherboard + bios version
is possible, as well as the dmesg output so we might be able to trigger on that)
Comment 8 Ben Levenson 2001-02-22 12:10:05 EST
The original oops was from a Dell PowerEdge 6300 server with 4 xeon cpus.
BIOS: Phoenix ROM BIOS PLUS 1.10 A06.
(Haven't determined the motherboard information yet.)

The problem is also reproducible on an Acer Altos with 2 cpus.
 BIOS: ((I assume Acer...any other brandname wasn't obvious) v3.0 (R01-C4 01 EN)
I know this is kind of cryptic, but the information is straight from the BIOS
product information screen) 

The lspci and dmesg information will be attached below.
