Bug#280746: aic79xx doesn't connect to motherboard adapter

[Axel Rose <axel_rose@sj.com>]

Hello,

first a protocol question.
How would I need to reply so the report goes back into the bug tracking
system?

The flaw with aic7xxx I reported has gone after I updated
to kernel-image-2.6.8-9-em64t-p4-smp

May I extend the story a bit.
I found performance problems with Gigabit clients. A single
client wrote phantastic 70 MByte/s but with two clients the
througput dropped to about 7 MByte/s each. Reading scaled
well.

One option was to check again with a 3Com optical Gigabit
card. Therefore I needed the acenic driver which is only
available with 2.9.6. I installed 2.6.10-rc2 from kernel.org
myself. The performance problems seemed to go away.
But only seemed. I tried with Samba, netatalk and the commercial
atalk package. After rebooting my server everthing seemed fine
but after a while performance dropped again.
I checked with/without ACPI, apic, mtrr, different cache setting,
serial ATA drives, different SCSI adapters, hardware SCSI raids,
ext3, xfs, reiserfs, Feodora, SuSE SLES 9, single CPU, 2 CPUs,
hyperthreading, ...
nothing helped

The only way to have good performance at the moment is with
reiserfs and only immediately after a reboot. Then it is even
stable.

Ony thing which bugs me is "free" only showing 3 Gigabit memory.
3200 Highmen, 800 lowmem. I have no idea how to influence this.

Also -- which configuration must be set to build a 64bit kernel?
Currently I just set processor type to Xeon.


Thanks for your help

Axel
