mjg59Booting a kernel should be fine, but we'll need to find out some way to get a console off it06:34
Keybukthey don't have usual PC BIOS do they?06:34
KeybukI guess Linux's support for EFMI isn't quite there yet?06:34
Keybuksurprised Intel haven't helped with that06:35
mjg59EFI is fine06:36
mjg59People have been using it to boot on IA64 for years06:36
mjg59And elilo should work fine on x8606:36
Keybukwhy no console then?06:36
mjg59Does EFI provide a sensible console?06:36
KeybukI don't know06:36
mjg59(Once passed to the kernel)06:36
mjg59I guess it might do - in which case vgacon probably works06:36

mjg59Ah, yeah, IA64 has VGAcon06:37

Keybukbcollins: is there any particular advantage to the amd64-k8 kernels over amd64-generic?07:57
BenCKeybuk: just that the compile-time options are more geared toward k807:58
MithrandirKeybuk: they give you IO-MMU support, for instance.07:59
KeybukMithrandir: btw, anything in particular you'd like me to test on this?  I know you've been doing some amd64 portability work08:05
MithrandirKeybuk: actually, yes.  If you run ddcprobe from the console, does it output sane values for you?08:05
Keybukyes, quite a bit08:05
Mithrandirpitti has some problems with his card, but I'm not sure which one that is yet08:06
Keybukhttp://rafb.net/paste/results/I1NxVx81.html08:07
Mithrandirhmm, so it appears it doesn't do edid for you either.. :-/08:08
Keybukinteresting08:08
Mithrandirany chance you could try ddcprobe from a i386 live cd?08:08
KeybukXorg.0.log says the nvidia driver has read stuff from EDID08:08
Keybukas in boot the Live CD and try?  or just run the i386 binary on this?08:09
Mithrandiras in, boot the live cd, pop out to the console and run sudo ddcprobe there08:12
Keybukright08:12
Keybukwill have to do that a bit later ;)08:12
Keybukwill give you the result tomorrow08:12
Mithrandirthe amd64 kernel doesn't have the vm86 syscall, so the i386 binary is useless on amd64.08:12

fishdishanother curiosity: there is this computer called TYAN VX 50. It has 8 slots for AMD Opteron processors. We are trying to fix Ubuntu to work with all the 8 processors. We have a problem though: 4 of the processors are connected to the motherboard with a PCI-E. Therefore there's a PCI-E to cross to 4 processors which are missing from the configuration09:35
cjbfishdish: "are missing from the configuration"?09:36
doko* Added support for Intel PRO/Wireless 3945ABG driver; this driver needs 16KB09:48
doko  stacks in kernel.09:48
dokoBenC: this is from ndiswrapper-1.9. do our kernels have 16kB stacks?09:48
BenCour stacksize is stock09:49
fishdishyeah... 4 processors are seen, 4 missing09:57
fishdishit seems that the PCI-E between the processors hides the add-on board from sight09:58
fishdishthis monitor sux even09:58
fishdishI have noticed that this is a kernel issue. Some ppl on #debian thoguht NUMA had to be reconfigured.09:59
fishdishbut i think NUMA has nothing to do with it10:00
fishdishwhich part of the kernel handles multiprocessing over PCI-E?10:00
fishdishTYAN sells their product with Linux (suse) but i'd like to use Debian/alternative10:01
fishdishTherefore in need to build  a custom kernel10:02
