Hi! I am testing a wireless adapter based on zd1211 on an embedded arm-based platform. I have compiled the driver for arm9 with the toolchain from emdebian.
I load the driver and configure essid and wep key without problems. But when I start a ping (from or against) the kernel oppses after some time. I have discovered that this behavior only reproduces when wep secutity is enabled. Either /proc/ksyms or /proc/modules are empty. This is the kernel oops: Unable to handle kernel paging request at virtual address 0010010d pgd = c0004000 [0010010d] *pgd=00000000 Internal error: Oops: 17 [#1] Modules linked in: zd1211_driver CPU:
