Graa, I reinserted the mailing lists there to the CCs, it may
be good for those guys too to be able to share whatever
hints they may have :P

As do we.
And that's a placebo effect for sure, the wlan should be able to
handle this ;)

I'm just mystified that an identical setup works.
I figured I'd upgrade the DRAC 4/I bios, as 1.20 is installed
and 1.30 is out, for what it's worth, but Red Hat seems to ship
some el mysterioso lockfile thing that I have to find somewhere...

Perfect.

Maybe I should clean the kernel conf up a bit, but nmi_watchdog=0
if it disables everythin a-ok didn't help :P

noapic and friends didn't help.

What does the old poke_blanked_console refer to?
I just rebooted the box with console=ttyS0,9600 as well (removed
above) and I still didn't see any issues.
Am I to assume pci=routeirq is truly so deprecated I shouldn't
bother with it even?
What's up with nmi_watchdog=0 and testing NMI watchdog ... CPU#0: NMI appears
to be stuck (0->0)! anyway?
Any hints on why the telnet interface spews only à at me after grub,
that or nothing?
I'd _really_ hate to launch these boxes 32-bit or without
working remote administration, so I'll still do a bit more
work but this is starting to suck :>
I'm sure no one has any guarantees this'll just be fixed in the
future and I can launch with 64 bits and schedule a reboot
later on...
Thanks!
And here's the ksymoops-decoded output:
ksymoops 2.4.9 on x86_64 2.6.12.2-amd64. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.12.2-amd64/ (default)
-m /boot/System.map-2.6.12.2-amd64 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed
