I use the latest and greatest 0.3.9 version :) Better. With the hostap_pci driver, after 2 and a half tries, I managed to get the backup to complete. But I still get lots of errors along the way: Jul 11 16:29:42 quark kernel: NETDEV WATCHDOG: wifi0: transmit timed out Jul 11 16:29:42 quark kernel: wifi0 Tx timed out!

Resetting card Jul 11 16:31:19 quark kernel: hostap_pci: wifi0: resetting card ... With the hostap_pci driver, the first time I tried to run the backup (rsync over ssh from workstation next to AP to T30 w/ prism card) my machine locked up after about 15 minutes. After rebooting, running fsck, and moving close to the AP I stopped X and tried to run it on virtual consoles. After about 15 minutes it stopped but the machine didn't lockup. It was totally idle w/ no network traffic. Running lsof | grep rsync tool about 20 seconds to respond. After stopping the interface and reloading the hostap_pci modules I was able to get network back. Interestingly rsync suddenly resumed where it left off and eventually completed (resetting the card all the way). Something about this rsync backup really tickles the system. Is this a known problem? Is it known to be the driver, firmware, or what? Could it be my access point (Linksys 802.11b 4 port switch BEFW11S4 v.2)? Thanks for your help. Personally I think I'm ok - now that I've sync'd up the backup should only take a minute or two now. But I'm willing to explore this if someone wants me to try some debugging. > See.. > > hostap_pci: 0.3.9 - 2005-06-10 (Jouni Malinen ) > PCI: Found IRQ 9 for device 0000:00:09.0 > hostap_pci: Registered netdevice wifi1 > wifi1: Original COR value: 0x0 > prism2_hw_init: initialized in 195 ms > wifi1: NIC: id=0x8013 v1.0.0 > wifi1: PRI: id=0x15 v1.1.1 > wifi1: STA: id=0x1f v1.7.4 > wifi1: Intersil Prism2.5 PCI: mem=0xe7800000, irq=9 > wifi1: registered netdevice wlan1 > wifi1: Deauthenticate all stations > wifi1: prism2_send_mgmt - device is not UP - cannot send frame > wlan1: Enabling ALC hostap_pci: 0.3.9 - 2005-06-10 (Jouni Malinen ) ACPI: PCI interrupt 0000:02:02.0[A] -> GSI 11 (level, low) -> IRQ 11 hostap_pci: Registered netdevice wifi0 wifi0: NIC: id=0x8013 v1.0.0 wifi0: PRI: id=0x15 v1.1.0 wifi0: STA: id=0x1f v1.4.9 wifi0: Intersil Prism2.5 PCI: mem=0xf8000000, irq=11 Mike
