Hi! Occasionally I get the following warning in ath5k_tx_queue(): [ 1156.930822] ------------[ cut here ]------------ [ 1156.988454] WARNING: at arch/x86/kernel/pci-nommu.c:34 nommu_map_page+0x2d/0x86() [ 1157.078085] Hardware name: [ 1157.112608] Modules linked in: arc4 ecb ath5k mac80211 ath cfg80211 rfkill led_class ipv6 w83697hf_wdt hostap_pci hostap lib80211 natsemi i2c_viapro i2c_core pcspkr ide_pci_generic ata_generic ehci_hcd uhci_hcd via_rhine sata_via r8169 usbcore libata mii [last unloaded: scsi_wait_scan] [ 1157.421492] Pid: 0, comm: swapper Not tainted 2.6.32vn1k #1 [ 1157.488261] Call Trace: [ 1157.517596] [<c011841d>] warn_slowpath_common+0x60/0x90 [ 1157.581244] [<c011845a>] warn_slowpath_null+0xd/0x10 [ 1157.641765] [<c01067b4>] nommu_map_page+0x2d/0x86 [ 1157.699196] [<dfa73d65>] ath5k_tx_queue+0x254/0x5ae [ath5k] [ 1157.766997] [<dfa747c0>] ath5k_tx+0x11/0x13 [ath5k] .....
