prism54 firmware fails to load on boot
Last modified: 2007-11-30 17:11:23 EST
Description of problem: Latest errata of udev prevents prism54 firmware from loading at boot up. Works ok after bootup has finished. Version-Release number of selected component (if applicable): udev-071-0.FC4.2 How reproducible: Every time Steps to Reproduce: 1. Possess machine with prism54 wireless card configured to work at boot (mine is PCI) 2. Install udev-071-0.FC4.2 3. Reboot Actual results: The prism54 wireless card is not initialised. The following appears in messages: Feb 9 17:59:33 hordein kernel: firmware_loading_store: unexpected value (0) Feb 9 17:59:33 hordein kernel: prism54: request_firmware() failed for 'isl3890' Feb 9 17:59:33 hordein kernel: wireless: could not upload firmware ('isl3890') Feb 9 17:59:33 hordein kernel: wireless: islpci_reset: failure Expected results: The prism54 wireless card should be initialised and work. The above messages should not be in the log file. Additional info: Discovered this when upgrading to kernel-2.6.15-1.1831_FC4, which pulled in the new udev. Also booted to the previous kernel-2.6.14-1.1656_FC4 with the new udev, same failure. On reverting to udev-058-1.0.FC4.1 and booting into kernel-2.6.14-1.1656_FC4 it all works again. Only appears to affect prism54 initialisation at bootup. If I subsequently: rmmod prism54 modprobe prism54 ifup wireless it all works. I'm not sure if the module even needs reloading.
and you have the file "isl3890" ??
Of course, otherwise it wouldn't have worked before the upgrade, after I downgraded back to udev-058 (which fixes it), or if I manually initialise the card while still running udev-071. The only time it doesn't work is at boot with udev-071. % ls -al /lib/firmware/isl3890 -rw-r--r-- 1 root root 93996 Aug 18 2004 /lib/firmware/isl3890 I don't think the firmware location can have moved again since it does work after boot with a manual ifup. I've checked the firmware from prism54.org and it is the latest version.
Please check /etc/udev/rules.d/50-udev.rules and make sure, this rule is NOT in there... ACTION=="add", SUBSYSTEM=="firmware", ENV{FIRMWARE}=="*", \ RUN+="/sbin/firmware_helper"
Those lines are not present in 058 (which is working for me). They are present, but are commented out with '#' in 071 (which isn't working). There don't appear to be any other firmware related lines in any files in that directory.
Just found this old bug. This was fixed with or during FC5, and is working correctly here with FC6.
