Red Hat Bugzilla – Bug 10866
PCMCIA kernel device is not allocating correct IRQs?
Last modified: 2008-05-01 11:37:55 EDT
My Dell laptop has been running 6.1 for about 4months, and I just upgraded to 6.2 using an iso CD. I have two CARDBUS ports on my Inspiron 7000, but for some reason Linux is only able to assign interrupts to one of them at a time. I have a scsi card and a 3com ethernet card. I was unable to track the problem when booting with dmesg, but when I remove and replace the card running dmesg provides this message: cs: cb_free(bus 32) cs: cb_alloc(bus 32): vendor 0x9004, device 0x6075 ROM image dump: image 0: 0x000000-0x0001ff, signature PCIR image 1: 0x000200-0x0003ff, signature PCIR cs: cb_config(bus 32) fn 0 bar 1: io 0xa00-0xaff fn 0 bar 2: mem 0x60050000-0x60050fff fn 0 rom: mem 0x60040000-0x6004ffff cs: cb_enable(bus 32) bridge io map 0 (flags 0x21): 0xa00-0xaff bridge mem map 0 (flags 0x1): 0x60040000-0x60050fff apa1480_attach(bus 32, function 0) aic7xxx: <Adaptec PCMCIA SCSI controller> at PCI 32/0/0 aic7xxx: I/O ports already in use, ignoring. apa1480_cs: no SCSI devices found scsi : 0 hosts. cs: cb_disable(bus 32) cs: cb_release(bus 32) I hope this provides some use for you. If you need any more information, please let me know, and I am completely willing to help in any way possible. Patrick Krautter patk@sig.net
This is a bug in the pcmcia package. Later pcmcia packages are known to solve this problem, but have not yet been fully tested for release purposes. This will be fixed with the next upgrade of the pcmcia package in the Red Hat kernels.
Any progress on this? I realise you're all busy guys...but we have had quite a few kernel updates over the past couple of months, and still no pcmcia-cs update. Thanks!
Hi Doug. This is a severe bug that really deserves a bugfix update. I simply cannot use RH6.2 on any of our laptops - the driver locks them all solid :-(
