Hello everybody,

seems like I have a problem with PCMCIA/PCCARD. If I transfer data to or fr=
om=20
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=20
(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=20
2.6.13-rc*/pcmciautils. The CF card is a Lexar 1GB.

root@logo:~# cat /proc/interrupts | grep yenta
 11:    5914154          XT-PIC  yenta, yenta, uhci_hcd:usb2, Intel=20
82801DB-ICH4, ide2

=2D-=20
Regards,
Christian
