No slab corruption this time (at least > not yet). Will switch to GFP_ATOMIC and retry w/ the new fw. Switching p54_set_tim to use GFP_ATOMIC seemed to help, a few quick tests resulted in no crashes and oopses; unfortunately ipv4 wasn't working all that well -- arp didn't work at all in fact. Tried the newer fw, but it does not seem to like my hw: usb 1-1.1: new full speed USB device using uhci_hcd and address 6 usb 1-1.1: New USB device found, idVendor=0846, idProduct=4200 usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 usb 1-1.1: configuration #1 chosen from 1 choice usb 1-1.1: firmware: requesting isl3886usb phy1: p54 detected a LM86 firmware p54: rx_mtu reduced from 3240 to 2392 phy1: FW rev 2.13.24.0 - Softmac protocol 5.9 phy1: cryptographic accelerator WEP:YES, TKIP:YES, CCMP:YES p54usb: probe of 1-1.1:1.0 failed with error -110 Last one working is: usb 1-1.1: new full speed USB device using uhci_hcd and address 5 usb 1-1.1: New USB device found, idVendor=0846, idProduct=4200 usb 1-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 usb 1-1.1: configuration #1 chosen from 1 choice usb 1-1.1: firmware: requesting isl3886usb phy0: p54 detected a LM86 firmware p54: rx_mtu reduced from 3240 to 2392 phy0: FW rev 2.13.1.0 - Softmac protocol 5.5 phy0: cryptographic accelerator WEP:YES, TKIP:YES, CCMP:YES phy0: hwaddr 00:30:f1:b1:09:e6, MAC:isl3886 RF:Frisbee wmaster0 (p54usb): not using net_device_ops yet phy0: Selected rate control algorithm 'minstrel' wlan0 (p54usb): not using net_device_ops yet udev: renamed network interface wlan0 to ap0 mon.ap0 (p54usb): not using net_device_ops yet cfg80211: Calling CRDA for country: US Disconnecting/reconnecting the wireless client resulted in this: > mac80211-phy0: failed to remove key (0, 00:1b:fb:12:34:56) from hardware (-12) followed later, when killing hostapd, by: > mac80211-phy0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-12) artur -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
