IRQ problem with PCMCIA

Hello everybody,
seems like I have a problem with PCMCIA/PCCARD. If I transfer data to or from
a CF card inserted via adapter system waits for interrupts most of the time:
Cpu(s): 21.2% us, 7.9% sy, 0.0% ni, 0.0% id, 1.7% wa, 69.2% hi, 0.0% si
This results in a very unresponsive system and a transfer rate of up to 1MB/s
(my new camera writes with up to 10MB/s on the card...).
Any idea what could be the reason? This is with 2.6.12/pcmcia-cs and with
2.6.13-rc*/pcmciautils. The CF card is a Lexar 1GB.
root at logo:~# cat /proc/interrupts | grep yenta
11: 5914154 XT-PIC yenta, yenta, uhci_hcd:usb2, Intel
82801DB-ICH4, ide2
