ipw2100 firmware broken by 038

ipw2100 firmware broken by 038

[Daniel Gryniewicz]

Hi, all

My ipw2100 firmware loading was broken by the update to 038.  I've since
downgraded back to 036 and it's working again.  Here's the error message
from 036:

Oct 14 18:38:50 athena wait_for_sysfs[13120]: error: wait_for_sysfs
needs an update to handle
the device '/class/firmware/0000:02:03.0' properly (4), please report to
<linux-hotplug-devel@lists.sourceforge.net>


And from 038:

Oct 14 18:34:18 athena wait_for_sysfs[10790]: either wait_for_sysfs
(udev 038) needs an update to handle the device
'/class/firmware/0000:02:03.0' properly (4) or the sysfs-support of your
device's driver needs to be fixed, please report to
<linux-hotplug-devel@lists.sourceforge.net>


With 036, the firmware loads anyway, and the card comes up.  With 038,
the firmware fails to load with an error from the card of:

Oct 14 18:34:18 athena eth1: Firmware 'ipw2100-1.3.fw' not available or
load failed.
Oct 14 18:34:18 athena eth1: ipw2100_get_firmware failed: -2

The firmware is unchanged between the two installs.  I'm running gentoo,
with 2.6.9-rc4-ck2.  I'll be happy to answer any necessary questions.

Thanks,
Daniel

This happens because of the increased timeout of 10 seconds, which is
also the maximum time the driver will wait for the firmware. We are trying to
read a file in the firmware class to be sure, the kernel has it created
but that file is unreadable. I will post a patch to the list in the next
few minutes, that will change to a stat() instead of an open().

Thanks for the report,
Kay
