Hmm...
Maybe it's a hardware problem, since I'm running my memory in Aggressive
mode (that's DualDDR mode...) and you are not...(since you have 1.5GB ram)
I'll have to run some tests...
When I leave the APIC enabled, I need to boot with "pci=noacpi" set.
Otherwise the 3com card pops to IRQ 21 (my realtek PCI is on 16 then)
and the ping times to a host on the local network (from the 3com -->
fixed IP) are very long --> 8000 to 20000 ms. That's probably also the
reason why the realtek card doesn't receive an IP-address via dhcp,
things are just slowed down somewhere...
| But any PCI network card (I've tried 2, from different brands) I use ends
| up using IRQ 16. I then disabled APIC mode in the BIOS, which would let
me
| use the PCI cards properly, but now only 900 or so Mb of the 1.5Gb RAM is
| seen by Linux (there is a warning about this in dmesg).
That's not a bug, it's exactly how the APIC works...
Looks like a bug to me --> with the ultra long ping times
it's the only way to get around the limitations of only 15 irq's...
the problem is if the ACPI does not work it also kills APIC,
atleast for now...
as for the Ram, it's because only enterprise kernel supports more
than ~1GB of ram. If you want the "standard" kernel to support
more you have to recompile it with highmem options turned on...
OK. I'll try that.
| Also, my usb mouse is not seen.
This is the probably because of ACPI problems...,
or try to move the mouse to another controller, since one of them
does not get asigned an irq at bootup (go figure...) and this is also
known at the kernel ML.
I've tried all the usb ports... eventually put the green PS2 adapter in
between and hooked to a ps2 port.
| I've also tried to compile the nvnet module, but it fails. The license is
| probably incompatible for mdk to add it to their kernels...
Yep,
It's almost GPL according to the license, but the nvnet source contains
one binary-only file wich makes it useless...
One PCI slot less...
| Oh yeah, this was all based on the 2.4.21.0.pre4.5mdk kernel.
| Do you think that I can enable the APIC mode with 2.4.21.0.pre4.6mdk?
you could try, so that we get more bug reports, and even better maybe some
solutions...
Oh well...
I'll be "out of office" for about a week starting tomorrow (or actually
later today),
but when I get back I'll start digging in to this problem again...
IMHO it has to been solved before 9.1 ships....
(along with many other things... of course)
