FreeBSD na ALIXu (DMA u HDD)

[Martin Salac]

Ahoj,

mam zajimavy postreh (+ maly namet na premysleni).

Instaloval jsem FreeBSD na ALIX (viz thread DMZ a Usporne PC ...) a
pozadavek byl pripojit misto CF normalni 2,5" ATA HDD (duvody neresme).
Zvolil jsem model ALIX2D3 (http://www.pcengines.ch/alix2d3.htm) -
v podstate osekle tuctove pecko s AMD Geode256 cipem, trema sitovkama,
ale hlavne miniATA (pro 2,5" HDD) patici vedle CF slotu.
Poridil 40ti zilovou ksandicku pro notebookove disky, nainstaloval
na stolnim PC system, zapojil do ALIXe, nabootoval z nej a projevil
se klasicky problem UDMA66/UDMA100 na "33" kabelu:

ad0: 28615MB <IC25N030ATDA04 0 DA4OA70A> at ata0-master UDMA100
ad0: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63
ad0: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63
ad0: FAILURE - READ_DMA status=51<READY,DSC,ERROR> 
error=84<ICRC,ABORTED> LBA=63
... (a porad dokolecka)

(cely vypis dmeg nize).

googlil jsem, jak vnutit systemu nahlizet na disk jako na UDMA33 
zariizeni uz pri bootu,
nasel jsem odpoved zde:
http://www.nabble.com/net5501-ATA-UDMA-mode-problem-with-FreeBSD-7.0-td17449010.html
nastavil do /boot/loader.conf
hw.ata.ata_dma_limit="2"  (coz je UDMA33)

... a efekt zadny - stale UDMA100.

Nesetkal se s tim nekdo, popr. netusi, proc mi option ata_dma_limit 
nezabrala?
(7.1-PRERELEASE)

Podotykam, ze jsem problem "obesel" vypnutim DMA v loaderu a po 
nabootovani nastavenim
ad0 na UDMA33 atacontrolem pomoc rc scriptu.

BTW - ALIX slape jako hodinky - muzu vrele doporucit na nenarocne 
routovani a bridge hlavne
u domacich siti,  zkusenosti s nim + FreeBSD mam velmi pozitivni - 
proste prima hracka :)

Zdravi

Martin

P.S. koho zajima info o systemu:

"BIOS" vypada takto (* * =aktivni option) :
(9) 9600 baud (2) 19200 baud *3* 38400 baud (5) 57600 baud (1) 115200 baud
(C) CHS mode *L* LBA mode *W* HDD wait (V) HDD slave *U* UDMA enable
(M) MFGPT workaround
(P) late PCI init
*R* Serial console enable
(E) PXE boot enable
(X) Xmodem upload
(Q) Quit
