I am building the TI wireless drivers from backports-3.12-1 for a 3.2 kernel. When I modprobe wlcore-spi I get a kernel crash. Has anyone encountered this? I found a similar problem here: http://marc.info/?l=linux-wireless&m=135212370625698&w=2 I tried adding the patch mentioned there to backports-3.12-1, but I get this build error: "error: 'struct wl1271' has no member named 'set_power'" Here's the crash: [ 98.325693] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 98.334171] pgd = c0004000 [ 98.337031] [00000000] *pgd=00000000 [ 98.340791] Internal error: Oops: 80000007 [#1] [ 98.345524] Modules linked in: wlcore_spi(O) wl12xx(O) wlcore(O) mac80211(O) cfg80211(O) compat(O) autofs4 [ 98.355661] CPU: 0 Tainted: G O (3.2.0) [ 98.364120] PC is at 0x0 [ 98.366846] LR is at wl12xx_set_power_on+0x30/0x150 [wlcore] [ 98.372764] pc : [<00000000>] lr : [<bf0b213c>] psr: 60000013 [ 98.372772] sp : cf445f28 ip : cf445ec8 fp : cf445f44 [ 98.384761] r10: c061c478 r9 : 00000000 r8 : cf6bd500 [ 98.390219] r7 : cf6bdac0 r6 : 00000000 r5 : cf2a4000 r4 : cf411480 [ 98.397039] r3 : 00000000 r2 : cf49bb6c r1 : 00000001 r0 : cf2a4008 [ 98.403861] Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel [ 98.411500] Control: 10c5387d Table: 8f3dc019 DAC: 00000015 [ 98.417503] Process firmware/ti-con (pid: 1330, stack limit = 0xcf4442f0) [ 98.424595] Stack: (0xcf445f28 to 0xcf446000) [ 98.429153] 5f20: c0076214 c0075c0c cf411480 cf2a4000 cf445f94 cf445f48 [ 98.437706] 5f40: bf0b8dc0 bf0b2118 cf2a4150 cf411480 cf445f94 cf445f60 c025c3ec c024e14c [ 98.446258] 5f60: c061cff0 cf444000 cf445fac cf470140 00000000 c025c5e4 00000013 00000000 [ 98.454809] 5f80: 00000000 00000000 cf445fbc cf445f98 c025c62c bf0b8ca4 00000001 00000000 [ 98.463362] 5fa0: cf445fbc cf6bd500 cf34db7c cf470140 cf445ff4 cf445fc0 c005554c c025c5f0 [ 98.471913] 5fc0: cf34db7c 00000000 cf470140 00000000 cf445fd0 cf445fd0 00000000 cf34db7c [ 98.480463] 5fe0: c00554c0 c0040108 00000000 cf445ff8 c0040108 c00554cc 00000000 00000000 [ 98.489002] Backtrace: [ 98.491616] [<bf0b210c>] (wl12xx_set_power_on+0x0/0x150 [wlcore]) from [<bf0b8dc0>] (wlcore_nvs_cb+0x128/0x944 [wlcore]) [ 98.502974] r5:cf2a4000 r4:cf411480 [ 98.506766] [<bf0b8c98>] (wlcore_nvs_cb+0x0/0x944 [wlcore]) from [<c025c62c>] (request_firmware_work_func+0x48/0x7c) [ 98.517787] [<c025c5e4>] (request_firmware_work_func+0x0/0x7c) from [<c005554c>] (kthread+0x8c/0x94) [ 98.527326] r5:cf470140 r4:cf34db7c [ 98.531089] [<c00554c0>] (kthread+0x0/0x94) from [<c0040108>] (do_exit+0x0/0x66c) [ 98.538902] r6:c0040108 r5:c00554c0 r4:cf34db7c [ 98.543743] Code: bad PC value [ 98.547128] ---[ end trace 9f4a33769e1819b4 ]--- -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
