Sorry Andrew, I am not sure which maintainer to contact about this. I
CCed gregkh for sysfs and Yi for ipw2200. Hopefully this is helpful.
BTW, I also found that none of my network drivers were recognized by
hal (lshal did not show their "net" entries) unless I set
CONFIG_SYSFS_DEPRECATED=y. I am running Ubuntu development (Feisty
Fawn), so it seems like I ought to be running pretty current hal
utilities: hal-device-manager 0.5.8.1-4ubuntu1. After
reenabling CONFIG_SYSFS_DEPRECATED, I am able to use my IPW2200
driver, in spite of this recursive locking message, so this INFO
message may not indicate a problem.

Does this show up on the 2.6.20-rc3 kernel too? thanks, greg k-h ^ permalink raw reply [flat|nested] 6+ messages in thread

Yes. Well, I can't speak for Miles on Ubuntu, but I have ipw2200 on openSUSE 10.2 (using ifplugd if that matters), and have to build my 2.6.20-rc3 with CONFIG_SYSFS_DEPRECATED=y in order to get an IP address (no idea whether it's a hald issue in my case). Likewise needed CONFIG_SYSFS_DEPRECATED=y with 2.6.19-rc-mm on SuSE 10.1.

Well, I'm using a distro released in 2006 that works just fine (Gentoo unstable, Debian unstable should also work. I think even Gentoo stable works too, but haven't tried that out...) thanks, greg k-h ^ permalink raw reply [flat|nested] 6+ messages in thread

Yes, HAL, udev, NetworkManager, ... from 10.2 works fine here, without that option set. Kay ^ permalink raw reply [flat|nested] 6+ messages in thread
