I think what is suspected is that the Cardbus card is holding its interrupt output active. This normally shares the same interrupt as the yenta socket status change interrupt, and, since we're listening for interrupts from the card, it causes this problem. A thought: can you reproduce this problem with 2.4? Has this cardbus card been used with other Linux kernels? On other machines? I suspect what you'll find is that any Linux kernel on any machine with this card will exhibit this problem - which would prove my theory. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 PCMCIA - http://pcmcia.arm.linux.org.uk/ 2.6 Serial core
