Package: firmware-brcm80211 Version: 20210315-3 Severity: normal This bug is mostly for documentation purposes.
When running a raspberry pi 4b as an access point, after a random period of time the on-chip firmware will crash and leave the wireless driver (brcmfmac) unusable until the chip is reset. The rest of the kernel is still fine, but the driver is unusable. Here's the firmware version that's in Debian 11 (bullseye): [ 16.365079] brcmfmac mmc0:0001:1: firmware: direct-loading firmware brcm/brcmfmac43455-sdio.clm_blob [ 16.373443] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4345/6 wl0: Sep 18 2020 02:27:58 version 7.45.221 (3a6d3a0 CY) FWID 01-bbd9282b Here's one example of the firmware crashing: Oct 12 17:40:06 wifi1 kernel: [263542.782712] brcmfmac: mmc_submit_one: CMD53 sg block write failed -84 Oct 12 17:40:06 wifi1 kernel: [263542.785401] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame Oct 12 17:40:52 wifi1 kernel: [263589.238359] brcmfmac: brcmf_sdio_hdparse: seq 77: max tx seq number error Oct 12 17:40:54 wifi1 kernel: [263591.678597] brcmfmac: brcmf_sdio_hdparse: seq 240: max tx seq number error Oct 12 17:40:54 wifi1 kernel: [263591.681542] brcmfmac: brcmf_sdio_hdparse: seq 241: max tx seq number error Oct 12 17:40:54 wifi1 kernel: [263591.684591] brcmfmac: brcmf_sdio_hdparse: seq 242: max tx seq number error Oct 12 17:40:54 wifi1 kernel: [263591.687778] brcmfmac: brcmf_sdio_hdparse: seq 252: max tx seq number error Oct 12 17:40:54 wifi1 kernel: [263591.690801] brcmfmac: brcmf_sdio_hdparse: seq 253: max tx seq number error Oct 12 17:40:54 wifi1 kernel: [263591.693780] brcmfmac: brcmf_sdio_hdparse: seq 254: max tx seq number error Oct 12 17:41:36 wifi1 kernel: [263633.105406] brcmfmac: brcmf_sdio_hdparse: seq 171: max tx seq number error Oct 12 17:50:57 wifi1 kernel: [264194.196126] brcmfmac: mmc_submit_one: CMD53 sg block write failed -84 Oct 12 17:50:57 wifi1 kernel: [264194.199127] brcmfmac: brcmf_sdio_txfail: sdio error, abort command and terminate frame Oct 12 17:52:12 wifi1 kernel: [264268.874931] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 12 17:52:14 wifi1 kernel: [264271.434963] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 12 17:52:14 wifi1 kernel: [264271.438681] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -110 Here's another one: Oct 9 15:59:31 wifi1 kernel: [1543849.606976] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 9 15:59:34 wifi1 kernel: [1543852.169907] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 9 15:59:34 wifi1 kernel: [1543852.173684] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -110 Oct 9 15:59:42 wifi1 kernel: [1543860.103164] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 9 15:59:44 wifi1 kernel: [1543862.663196] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 9 15:59:44 wifi1 kernel: [1543862.666950] ieee80211 phy0: brcmf_cfg80211_get_station: GET STA INFO failed, -110 Oct 9 15:59:57 wifi1 kernel: [1543875.207367] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Oct 9 15:59:59 wifi1 kernel: [1543877.767429] ieee80211 phy0: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg failed w/status -110 Notice how the crashes happened 3 days apart. The crash prior to Oct 9th happened a full month before, so I no longer have logs. I haven't found any kind of pattern in timing. I'm currently trying a newer Cypress firmware (from unstable), so we'll see if it also has the same crash.
