Description hgh02351 2000-04-26 16:10:01 UTC

On M/B:ABIT BP6 based PC,
  3.4-RELEASE works fine with SMP + APM 
configerd kernel.
  but 4.0 did panic at every boot.
  Then "device apm" removed, it works fine.

panic message contains ;
current process    =  160 (apmconf)
interrup mask      =  none<-SMP: xxx
trap number        =  12
panic : page fault
mp-lock = 01000002; cpuid = 1;lapic.id=01000000

How-To-Repeat: Just do boot using SMP + APM
configerd 4.0 kernel on ABIT BP-6 based PC.
or, on some/any SMP PC ?

Does this still occur with more recent releases?

Hi!

I'm just browsing through the PR-database, and found this PR.

I have similar problems with my brand new Gigabyte GA-6VXDC7 mainboard
(2x800 P-III, 512 MB RAM) running FreeBSD 4.4-RC from this morning (Sun=20
27th August). APM is detected

....
apm0: <APM BIOS> on motherboard
apm: found APM BIOS v1.2, connected at v1.2
....

and when I enable (apm -e enable) or query (just apm) on the console=20
the complete machine locks without any further information (DDB is=20
compiled in)!

A quick test ans verification with the same kernel config, but SMP=20
support commented out seems to work.

Please can you help? Any further ideas for testing? The BIOS is the=20
last one provided from Gigabye? I only found a Google message in the=20
Linux context (2000-12-30) whis stated:

.......
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.13)
apm: disabled - APM is not SMP safe.
.......

Is this perhaps a BIOS problem?

Best regards

Lars

Submitter says that this was fixed around the time of 4.1.1-RELEASE.
