Here is a bit more information. It looks like there have been some kernel changes. It looks like the ath_pci module is now under the "weak-updates" directory. Please tell the kernel guys that we don't want "weak" signal, we want "strong" signals. ;-) /lib/modules/2.6.22.9-0.4-default/weak-updates/ath/ath_pci.ko /lib/modules/2.6.22.9-0.4-default/weak-updates/ath_rate/onoe/ath_rate_onoe.ko /lib/modules/2.6.22.9-0.4-default/weak-updates/ath_rate/amrr/ath_rate_amrr.ko /lib/modules/2.6.22.9-0.4-default/weak-updates/ath_rate/sample/ath_rate_sample.ko /lib/modules/2.6.22.9-0.4-default/weak-updates/ath_hal/ath_hal.ko /lib/modules/2.6.22.9-0.4-default/kernel/drivers/md/multipath.ko /lib/modules/2.6.22.9-0.4-default/kernel/drivers/md/dm-multipath.ko -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
