Tulip 21040 hangs with ifconfig promisc

This is:
Linux version ~2.6.4 (Red Hat Linux 3.3.2-1)) SMP kernel, UNI CPU.
(as of Mar 12 in bkcvs/linux-2.5/).

Acorp VIA77 mobo - AMD-K6 3D 500 MHz + VIA MVP3 chipset.
SMC EtherPower^2 (dual DECchip 21040 + 21050 PCI-PCI bridge)
All running out of ramdisk.

Doing "ifconfig eth0 promisc" kills the ethernet. Interrupts are gone,
nothing in dmesg. -promisc nor ifconfig down/up doesn't fix it,
only driver rmmod/insmod does.

de2104x PCI Ethernet driver v0.6 (Sep 1, 2003)
eth0: 21040 at 0xca81e000, 00:00:c0:d8:66:e0, IRQ 11
eth1: 21040 at 0xca820000, 00:00:c0:16:1b:c0, IRQ 12
eth0: enabling interface

eth0: set mode 0xfffc0000, set sia 0x8f01,0xffff,0x0
eth0: link up, media 10baseT-HD
device eth0 entered promiscuous mode

Any idea?
