Likely some wireless ioctl compat layer bug in the kernel.
Is this 32/64 interop? The kernel has never been fixed and never will
be. New wireless tools should "support" this, but imnsho you're *much*
better off compiling 64-bit wireless tools.
There was a patch for this kind of issue from Masakazu Mokuno
that went in 2.6.22 or 2.6.23 that was touching that part. I don't
think he went in the stable series, but probably should have. There
are other potential cause of problem here, and I suspect he might get
the same error with 64 bits userspace.
Can you give me the exact error text as reported by iwconfig ?
I'll probably have to send you a test version to see what's happening
under the cover.
Please find this in-lined below (with key protected):
# iwconfig eth2
eth2 IEEE 802.11b/g ESSID:off/any Nickname:"zd1211"
Mode:Managed Frequency:2.462 GHz Access Point: Invalid
Bit Rate=1 Mb/s
Encryption key:<too big>
# iwconfig eth2 essid dixieland key "GGGGGGGGGG"
# iwconfig eth2
eth2 IEEE 802.11b/g ESSID:off/any Nickname:"zd1211"

If I try to scan for APs using iwlist, I get one AP listed, before a bus
error occurs. This of course, does not suggest that the problem is with
the driver, but I mention it for the record.
This is an unaligned data access in the userland tools.
Try to catch it with GDB and give us ths backtrace.
For Jean.
Definitely, it sounds familiar.
This is that I need :
o version of the kernel
Debian sparc64 2.6.22 (built myself, using make-kpg, to include the driver)
o version of the driver if not stock driver
As stock with the kernel described above
o version of Wireless Tools (iwconfig --version).
Most likely, you need to upgrade your Wireless Tools to
version 29 which fixes this 32/64 interop problem.
With the latest kernel and the latest wireless tools, the only
known bugs are the two ESSID bugs.
I think I'm right for version:
# iwconfig --version
iwconfig Wireless-Tools version 29
Compatible with Wireless Extension v11 to v22.
Kernel Currently compiled with Wireless Extension v22.
eth2 Recommend Wireless Extension v20 or later,
Currently compiled with Wireless Extension v22.
Hope that helps.

Shaddy
