ath_pci? Sounds like madwifi...you'll have to install a new package from wherever you got it that matches the new kernel. If that doesn't work, you'll have to seek support from them -- sorry, we can't support it here. drivers/net/wireless/ath5k/base.c line 2504:
static struct pci_driver ath_pci_drv_id = {
.name = "ath_pci",
.id_table = ath_pci_id_table,
.probe = ath_pci_probe,
line 2576:
static int __init init_ath_pci(void)
{
int ret;
ret = pci_register_driver(&ath_pci_drv_id);
if (ret) {
printk(KERN_ERR "ath_pci: can't register pci driver\n");
return ret;
}
Related to bug 254192? (See comment 44 in that bug) ath_pci: sorry, was thinking of the actual module name (i.e. ath_pci.ko) Re: bug 254192 comment 44, I think that may explain this. Please try the test kernels here: http://koji.fedoraproject.org/koji/buildinfo?buildID=22061 Do these restore the lost functionality? Yes. The -31 kernel does restore the lost functionality.

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20071018 Fedora/2.0.0.6-12.fc8 Firefox/2.0.0.6 Description of problem: When running kernel version 2.6.23.1-18, my Atheros AR5211 wireless card was recognized and worked as expected. It was probed and recognized in dmesg and NetworkManager was able to connect it to my wireless network. After upgrading to kernel 2.6.23.1-23, I now get an error in dmesg that the probe failed with error -22 and NetworkManager is unable to control the card. lspci -v still shows the correct hardware, but it does not work. I don't know if it is relevant or not, but i notice in the -18 kernel that works, the ath_pci is detected before acpi assigns the irq, and in -23 which fails, acpi disabled the interrupt before ath_pci ran. 2.6.23.1-18 dmesg ath_pci 0000:02:02.0: AR5211 chip found: mac 4.4 phy 3.0 ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16 2.6.23.1-18 lspci -v 02:02.0 Ethernet controller: Atheros Communications, Inc.

Install 2.6.23.1-23 or above kernel (tested up to -30) 2. Reboot 3. Run dmesg | grep ath_pci to see the failure Actual Results: wireless network does not work Expected Results: wireless network should work as in previous kernel versions (-18 and lower) Additional info: Toshiba Satellite P25-S507 laptop
