Interrupt storm when inserting PCMCIA Memory Card Adapter

Hi list,
I just bought a brand new PCMCIA based multi-card reader for use at
work. It's a "Delock Card Reader PCMCIA 16in1" for SM, MS, SD, xD and
T-Flash based memory cards [1].
I used to have a Sitecom multi-card reader before, which worked fine.
But the new card does not behave as wanted:
Sep 15 12:29:28 pegasus kernel: ata2: < Memory Card
Adapter II> at port 0x4000-0x400f irq 11 function 0 config 1 on
pccard0
Sep 15 12:29:28 pegasus kernel: ad4: 240MB <Memory Card Adapter II
S2-V1.01> at ata2-master PIO1
Sep 15 12:29:28 pegasus kernel: Interrupt storm detected on "irq11:
cbb0 cbb1+++"; throttling interrupt source
Are there any hints how to solve this (besides kicking the card back
to the vendor)?
The system behind: IBM ThinkPad t40 with FreeBSD 6.0-BETA4 (Same
happens on identical hardware with FreeBSD 5.4).

Two of the most famous products of Berkeley are LSD and Unix.
I don't think that this is a coincidence.
