While creating IBSS network - execution of command: ./load; iwconfig eth1 essid test mode ad-hoc key off such message can be seen: ipw2200: Already sending a command ipw2200: failed to send TX_POWER command Few seconds later another message is displayed: ipw2200: Overriding invalid channel Execution of "iwconfig eth1 channel 1" creates IBSS network without any problems.

In Fedora2 IBSS network can be created as said above but in SuSE execution of ./load; iwconfig eth1 essid test mode ad-hoc key off cause mode to change for a while to ad-hoc and after half a second back to managed so IBSS network cant be created. The same situation occurs if command is separated to two commands, executed very quickly after each other: ./load iwconfig eth1 essid test mode ad-hoc key off
I get the same error after resuming from hibernate (S4) on a IBM Thinkpad X40. I need to reboot the machine to get the card working again: ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 0.19 ipw2200: Copyright(c) 2003-2004 Intel Corporation ACPI: PCI interrupt 0000:02:02.0[A] -> GSI 11 (level, low) -> IRQ 11 ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection ipw2200: failed to send TX_POWER command ipw2200: failed to send TX_POWER command ipw2200: failed to send TX_POWER command ipw2200: failed to send TX_POWER command ipw2200: failed to send TX_POWER command ipw2200: Unable to initialize device after 5 attempts. ipw2200: failed to register network device ipw2200: probe of 0000:02:02.0 failed with error -5
Comment #3 is talking about a different bug. See bug 363.
Request from the bug scrub was to re-test this will distro network scripts disabled. Log: logics problem is two fold logics 1) the distribution is setting the mode to managed logics 2) while it is resetting the device back to managed, additional commands are coming in at the request of the user, which can not be executed due to concurrency issues, and so the messages are displayed |<-- cis_ has left irc.freenode.net ("ChatZilla 0.9.61 [Mozilla rv:1.7.2/20040803]") logics we need a retest with all network configuration scripts disabled soopel ok rustyl_ I susupect the correct way to test with Suse, is to use the tools they provide (GUI tools) instead of directly calling the command line tools
Retested with disabled network configuration scripts. Attachment of dmesg output below (debug = 0xffff). The problem with changing mode back to managed doesnt exist anymore but messages like below still are displayed: ipw2200: Already sending a command ipw2200: failed to send TX_POWER command Few seconds later another message is displayed: ipw2200: Overriding invalid channel Repro: ./load debug=0xffff; iwconfig eth1 essid lala mode ad-hoc key off

You may still see the messages relating to attempts to send a command while one is active, but the driver should recover. There was a race condition that could occur that would result in the driver entering a state where it thought a command was being sent during a NIC reset (as occurs during mode change)
