current@ people,
5.0-DP2-disc1.iso with my ASUS P2L97-DS ACPI BIOS Revision 1008 Dual cpu box
boots OK :-) But 4.7-RELEASE & stable produce a boot panic with a kernel
where ATA + dual processor are both enabled.
Does that mean there is code in 5.0 that could be
retro-fitted to Stable, to help others with SMP + ATA ?
(I'm not asking for myself, I'll stay with current now installed :-)
Further notes for anyone interested:
4.7-RELEASE GENERIC boots OK in single cpu mode.
Stable boots in dual cpu mode with this patched out:
#device ata0 at isa? port IO_WD1 irq 14
#device ata1 at isa? port IO_WD2 irq 15
#device ata
#device atadisk # ATA disk drives
#device atapicd # ATAPI CDROM drives
#device atapifd # ATAPI floppy drives
#device atapist # ATAPI tape drives
#options ATA_STATIC_ID #Static device numbering
& this added:
options DDB
options INCLUDE_CONFIG_FILE
options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O
makeoptions DEBUG=-g
Neither stable nor 4.7-RELEASE will support both ATA + SMP.
I added the patch below to my stable, which moved the boot panic
to occur a little later. It shows the code in stable is broken,
as I see the "ata_pmode called with no pointer"

PS I bought this machine at auction recently, I've reset the BIOS
to setup defaults, but not done a BIOS upgrade, got a bit bogged
down in Asus new site, suspect I might have to register myself there.
