Hallo, I have a problem with four WAP321 at various locations. All APs are configured with two WLANs and two VLANs. The APs are connected via the Cisco power supply. After about 7 days, the AP stops responding and you have to separate from the power supply. After the APs work again for about 7 days. Resetting the AP did not change anything. Problem with firmware 1.0.3.4 and 1.0.4.2. crashdump with Software Version: 1.0.3.4 Crash Log: Uptime of the AP: 7 Days, 0 Hours, 3 Minutes and 38 Seconds CPU Unable to handle kernel paging request for process = swapper and pid = 0 epc == 800769c4, ra == c0519000 Stack Trace: [<00000000c0519000>] - wlc_txc_scb_free+0x50/0x8c [wl] [<00000000c051affc>] - wlc_txc_scb_init+0xcc/0xd4 [wl] [<00000000c054c484>] - wlc_scbinit+0x98/0xcc [wl] [<00000000c054dec8>] - wlc_userscb_alloc+0xc0/0x2d0 [wl] [<00000000c054e87c>] - wlc_scblookup+0x11c/0x1c0 [wl] [<00000000c057c024>] - wlc_ap_authresp+0x68c/0x9d0 [wl] [<00000000c0535264>] - wlc_recvctl+0x1158/0x28b8 [wl] [<00000000c0676ae4>] - wlc_recv+0x5f8/0x808 [wl] [<00000000c067f7f8>] - wlc_dpc+0x6c8/0xb30 [wl] [<00000000c06794c0>] - wl_dpc+0x50/0x164 [wl] [<000000008002f09c>] - tasklet_action+0x70/0xf4 [<000000008002ea20>] - __do_softirq+0x80/0x110 [<000000008002eb18>] - do_softirq+0x68/0x70 crashdump with Software Version: 1.0.4.2 Crash Log: Uptime of the AP: 7 Days, 23 Hours, 42 Minutes and 8 Seconds CPU Unable to handle kernel paging request for process = swapper and pid = 0 epc == 800769d0, ra == c0519000 Stack Trace: [<00000000c0519000>] - wlc_txc_scb_free+0x50/0x8c [wl] [<00000000c051affc>] - wlc_txc_scb_init+0xcc/0xd4 [wl] [<00000000c054c534>] - wlc_scbinit+0x98/0xcc [wl] [<00000000c054df78>] - wlc_userscb_alloc+0xc0/0x2d0 [wl] [<00000000c054e92c>] - wlc_scblookup+0x11c/0x1c0 [wl] [<00000000c057c0fc>] - wlc_ap_authresp+0x68c/0x9d0 [wl] [<00000000c053526c>] - wlc_recvctl+0x1158/0x28b8 [wl] [<00000000c0676d94>] - wlc_recv+0x5f8/0x808 [wl] [<00000000c067faa8>] - wlc_dpc+0x6c8/0xb30 [wl] [<00000000c0679770>] - wl_dpc+0x50/0x164 [wl] [<000000008002f09c>] - tasklet_action+0x70/0xf4 [<000000008002ea20>] - __do_softirq+0x80/0x110 [<000000008002eb18>] - do_softirq+0x68/0x70
