 When testing with a recent kernel (such as
 kernel-3.0.0_xo1.75-20111107.1918.olpc.4fbb7db.armv71) with the WLAN
 associated with an access point, I occasionally see a kernel crash.

 The base OS is os883.  Firmware is Q4C03ma.

 On the screen, I see the following stack trace:

 lbs_set_11d_domain_info + 0xe8

 lbs_reg_notifier + 0x8c

 wiphy_update_regulatory + 0x428

 wiphy_register + 0x354

 lbs_cfg_register + 0xd4

 lbs_start_card + 0x70

 if_sdio_probe + 0xdc4

 etc..

 I was not able to trigger SysRq to get more information.

 I have also seen this with earlier suspend/resume kernels.
