fc1_x86_64 preview on tyan thunder k8w (S2885ANRF REV .03)

[Rob Myers]

hello-

thanks for getting fedora working on x86_64!

i've tried to search linux-kernel archives, archives at www.x86-64.org,
and bugzilla at redhat.com, but i haven't found all the answers i'm
looking for.  is there a faq anywhere for linux on x86_64 or even for
fedora on x86_64?

my system is running fedora core 1 x86_64 preview updated to kernel
2.4.22-1.2129.nptlsmp on dual opteron 248 2.2GHz tyan thunder k8w with
4gb of ram.  acpi=off is passed to the kernel as a boot parameter or
else it hangs with dma errors during or after boot.

first, i've got 4gb of ram in the machine, but cat /proc/meminfo only
reports 3.5gb free:
        total:    used:    free:  shared: buffers:  cached:
Mem:  3539730432 91926528 3447803904        0 24104960 29126656
Swap: 4186656768        0 4186656768

is this a bug or am i missing something?  i also tried passing mem=4G
with no success

second, AMD-8111 IDE has dma timeouts if acpi is enabled.  is this a
known issue?

third, just to report my experience: (i think these are known issues)

- the onboard broadcom 5703 based gigabit does not work properly with
tg3, but broadcom 5701 based 3Com 3C996B-T does work properly with tg3.
- the onboard sil SATA controller does not work
- kernel-smp-2.6.0-0.test11.1.100.x86_64.rpm from
http://people.redhat.com/arjanv/2.5/RPMS.kernel does not boot, just
oopses to the console.

thanks for any help, info or pointers.

rob.

ps- dmesg attached in case that will provide any useful info.
