re3 Watchdog timeout Openbsd 5.0+ Commell LE-565

[garutilorenzo]

i'm experiencing problem with openbsd 5.0+ and flashboot on a commell LE-565 board (http://www.commell.com.tw/Product/SBC/LE-565.HTM) . The board has 4 RTL8110S Network card, the problem is that when i attach the fourth network card the kernel says:

re3 Watchdog timeout

the interface is unusable (no response to ping, ssh and dhclient request ecc)

Until openbsd/flashboot 4.9 no problem experienced.
Openbsd 5.3 (no flashboot) runs normally on that motherboard.

this output is from dmesg:

Hi.

Hi Johan,

I have not yet tested the code from the last commit.
In the next few hours i get the new code and i start a new build.

Hi Johan,

I've tested the new version, the problem still persist.
I use a GENERIC Kernel. The only thing I've changed is the wd* at pciide from:

wd* at pciide? flags 0x0000

to:

wd* at pciide? flags 0x0ff0

for a problem with the DMA timeout when i use compact flash (KINGSTON).
