Thanks for the comparison, very interesting!

I am taken aback by the fact that you're using a vpn1411. I have some
net4501 and some Soekris crypto accelerators (vpn1211, vpn1401 and
vpn1411). All vpn cards are detected without problems by m0n0wall (1.0
and 1.1b13) _except_ the vpn1411 card. Kernel output:

hifn0 mem 0xa0008000-0xa000ffff,0xa0002000-0xa0003fff,0xa0000000-0xa0000fff irq 10 at device 16.0 on
pci0
hifn0: proc unit did not reset
hifn0: proc unit did not reset
hifn0: crypto enabling failed
device_probe_and_attach: hifn0 attach returned 6

However, that card works fine with NetBSD 2.0F (actually, I'm not sure
if it really works, but at least it's detected correctly.):

hifn0 at pci0 dev 16 function 0: Hifn 7955, rev. 0
hifn0: 3DES/AES, 32KB dram, interrupting at irq 10

so I think it's not faulty.

The vpn1401 card which uses the same Hifn 7955 chip as the vpn1411 is
detected by m0n0wall just fine. Hmm...

Strange. I can't reproduce this with my vpn1401 card. After sending
some 10^2 MB through the IPsec tunnel it still works, no lock up at
all.

LOL, yes! Is this possible? It's better not to use any Soekris crypto
cards with a net4801 because without it's much faster? Or was it just
a typo?


Cheers, Jukka
