However, trying a wl1281 module and enabling PLT mode it boots ok but after a couple of seconds the below crash is seen. Seems like a similar crash to the one I have seen before,right? I do have patch 7/6 applied now. sh-4.4# calibrator wlan0 plt power_mode on [ 57.198492] wlcore: power up [ 57.757871] wlcore: firmware booted in PLT mode PLT_ON (PLT 7.3.10.2.142) sh-4.4# sh-4.4# sh-4.4# ca[ 86.485020] ------------[ cut here ]------------ [ 86.490334] WARNING: CPU: 0 PID: 502 at drivers/net/wireless/ti/wlcore/main.c:806 wl12xx_queue_recovery_work+0x64/0x6c [wlcore] [ 86.502047] Modules linked in: arc4 pru_rproc wl12xx pruss_intc wlcore mac80211 cfg80211 pruss ti_am335x_tsc ti_am335x_adc musb_dsps musb_hdrc udc_core usbcore phy_am335x phy_generic phy_am335x_control usb_common pm33xx wkup_m3_ipc snd_soc_simple_card snd_soc_simple_card_utils wkup_m3_rproc remoteproc omap_aes_driver crypto_engine omap_sham omap_crypto ti_emif_sram pruss_soc_bus snd_soc_tlv320aic3x wlcore_sdio matrix_keypad rtc_omap ti_am335x_tscadc omap_wdt matrix_keymap musb_am335x sch_fq_codel [ 86.546686] CPU: 0 PID: 502 Comm: irq/71-wl12xx Not tainted 4.14.40-01415-g47241db-dirty #119 [ 86.555312] Hardware name: Generic AM33XX (Flattened Device Tree) [ 86.561540] Backtrace: [ 86.564119] [<c010baf8>] (dump_backtrace) from [<c010bd5c>] (show_stack+0x18/0x1c) [ 86.571838] r6:00000000 r5:bf30a5fc r4:00000000 r3:00000000 [ 86.577661] [<c010bd44>] (show_stack) from [<c0805dd0>] (dump_stack+0x20/0x28) [ 86.584994] [<c0805db0>] (dump_stack) from [<c01287bc>] (__warn+0xdc/0x104) [ 86.592121] [<c01286e0>] (__warn) from [<c012880c>] (warn_slowpath_null+0x28/0x30) [ 86.599838] r10:c0d4ea79 r8:c0169590 r7:db0f1558 r6:dc716ec8 r5:dc716d38 r4:dc716d00 [ 86.608019] [<c01287e4>] (warn_slowpath_null) from [<bf2f5468>] (wl12xx_queue_recovery_work+0x64/0x6c [wlcore]) [ 86.618630] [<bf2f5404>] (wl12xx_queue_recovery_work [wlcore]) from [<bf2f5a18>] (wlcore_irq+0x21c/0x234 [wlcore]) [ 86.629157] r4:dc716d00 r3:db164010 [ 86.633009] [<bf2f57fc>] (wlcore_irq [wlcore]) from [<c01695b4>] (irq_thread_fn+0x24/0x3c) [ 86.641441] r7:db0f1558 r6:db0f1500 r5:00000001 r4:db1b8680 [ 86.647236] [<c0169590>] (irq_thread_fn) from [<c0169260>] (irq_thread+0x10c/0x1ec) [ 86.655044] r6:db0f1500 r5:00000001 r4:db1b8680 r3:db623600 [ 86.660875] [<c0169154>] (irq_thread) from [<c014526c>] (kthread+0x11c/0x154) [ 86.668148] r10:c0169154 r8:db1b8680 r7:db1b8958 r6:db1b8600 r5:00000000 r4:db1b8940 [ 86.676104] [<c0145150>] (kthread) from [<c0107f68>] (ret_from_fork+0x14/0x2c) [ 86.683479] r10:00000000 r9:00000000 r8:00000000 r7:00000000 r6:00000000 r5:c0145150 [ 86.691451] r4:db1b8600 r3:ffffffff [ 86.695099] ---[ end trace dea7def5777109c9 ]--- BR, Eyal
