Description of problem: irq problem when inserting a pcmcia USB 2.0 card Version-Release number of selected component (if applicable): All of 2.6.5-1.358, 2.6.8-1.521, 2.6.9-1.6_FC2 How reproducible: Every time. Steps to Reproduce: 1. Boot system. kernel choice seems not to matter. apm=off only option specified. That seemed to be necessary during install and was carried into grub.conf from there. 2. Test network. All is good. 3. Insert card. See message in current terminal that IRQ 11 is disabled. 4. Test network. Notice that mini-pci wireless card is now disconnected from access point and nothing I've tried other than rebooting without the pcmcia card brings it back. 5. Plug usb device (external hard drive) into pcmcia card. It is not seen. Actual results: Neither pcmcia USB card nor wireless NIC work any more Expected results: Both devices should work Additional info: This is on a Dell 5100 laptop. This worked under Core 1 and RH9 though in those cases I was using custom kernels to get the latest acpi patches in and because I was dual booting at the time and needed to enable NTFS. Now that my laptop is M$-free I do not need to do that any more. The mini-pci is a Dell something that uses a broadcom chipset. I use the linuxant driverloader to support it. Key message from dmesg suggests: irq 11: Please try booting with acpi=off and report a bug Turning off acpi did not fix the problem though I have not checked dmesg messages in that situation to see what else it might say.
For what it's worth, the problem continues in Fedora Core 3.
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
Still a problem in FC3. I have upgraded to kernel 2.6.11-1.14_FC3 and also tried to put irqpoll and irqfixup on the boot line. One promising thing, using those options, the card works OK (that is, USB works) if I boot with it in the slot though the NIC still gets confused shortly after boot. If I boot with the card outside the slot and insert it, the card doesn't work properly (that is, USB doesn't work) and the NIC loses as well.
May as well close it. The card has now died and I don't plan on buying another.
