I have Knoppix 5.0.1 install on my hard-drive. I have an IBM ThinkPad 390 2626-70U laptop. When I boot from the hard-drive and a certain PCMCIA wireless card is installed, a "Netgear 802.11b Wireless PC Card 16-bit PCMCIA MA401" v2.5, the kernel hangs with the following error:

Unexpected IRQ trap at vector 30

If I boot from the Knoppix 5.0.1 CD I don't experience this problem.

This problem sounds similar to what's described in a message with the subject, "2.6.17 - hostap_cs: unexpected IRQ trap at vector b0 and kernel freeze " at this URL: http://www.uwsg.iu.edu/hypermail/lin...06.2/1640.html

The workaround for this problem is to pull the wireless card while the system is booting then after booting insert the card and run 'sudo pump -i eth0'.

Can anyone give me a solution or better workaround for this problem?

Thanks!
Joel
