while searching for the kmod with the same md5sum as the one used on the device, I've found out, that OpenWrt is not using upstream ath10k kernel module, so I don't want to make more noise on the ath10k mailing list[1], so let's continue this topic on openwrt-devel where it probably belongs. > Can you use gdb to print out the lines of code around that crash site in > t2h_msg_handler? > > [<87622780>] ath10k_htt_t2h_msg_handler+0x27e0/0x31dc [ath10k_core] (gdb) l *ath10k_htt_t2h_msg_handler+0x27e0 0x227b0 is in ath10k_htt_rx_handle_amsdu (/ath10k-ct-2019-03-25-2e917efb/ath10k-4.19/htt_rx.c:374). 369 370 /* FIXME: we must report msdu payload since this is what caller 371 * expects now 372 */ 373 skb_put(msdu, offsetof(struct htt_rx_desc, msdu_payload)); 374 skb_pull(msdu, offsetof(struct htt_rx_desc, msdu_payload)); 375 376 /* 377 * Sanity check - confirm the HW is finished filling in the 378 * rx data. > > [<8764901c>] ath10k_ce_rx_update_write_idx+0x9c/0xc4 [ath10k_core] (gdb) l* ath10k_ce_rx_update_write_idx+0x9c 0x4904c is in ath10k_ce_rx_update_write_idx (/opt/devel/openwrt-gluon/gluon.git/openwrt/build_dir/target-mips_24kc_musl/linux-ath79_generic/ath10k-ct-2019-03-25-2e917efb/ath10k-4.19/ce.c:763). 758 if (((cur_write_idx + nentries) & nentries_mask) == dest_ring->sw_index) 759 nentries -= 1; 760 761 write_index = CE_RING_IDX_ADD(nentries_mask, write_index, nentries); 762 ath10k_ce_dest_ring_write_index_set(ar, ctrl_addr, write_index); 763 dest_ring->write_index = write_index; 764 } 765 EXPORT_SYMBOL(ath10k_ce_rx_update_write_idx); 766 767 int ath10k_ce_rx_post_buf(struct ath10k_ce_pipe *pipe, void *ctx, > I can figure out which message caused it I can add debugging and/or > protective code.
