wifi and M.2 Sata adapter issuies

Chip Platform Rockchip

Hi, everyone, couple of questions here

  1. In dmesg output I observe lots of this:
[  102.088596] Error getting the SSID
[  102.596428] _tdata_psh_info_pool_deq 200: Out of tdata_disc_grp
[  102.596438] dhd_tcpdata_info_get 1092: No more free tdata_psh_info!!

Formally wireless works stable both 2.4 and 5GHz, but I’m sure it should not constantly give this output.
The only mod I added to 4.4.154 kernel was NFSD support.

  1. Any high load to HDD connected over Firefly’s SATA adapter result in system hang with adaper’s blue led on permanently.
    Moreover, hdparm -tT /dev/sda1 returns extremely slow timing:
/dev/sda1:
 Timing cached reads:   2588 MB in  2.00 seconds = 1293.83 MB/sec
 Timing buffered disk reads: 330 MB in  3.00 seconds = 109.87 MB/sec

Please share you considerations

Is there an overtemperature of the SATA adapter?
Are there any steps to reproduce your problem?

Suppose no overtemperature occurs - I put a small fin heatsink on ASM1061 chip and maximim that IR thermometer read is 37C. Firefly hangs when Transmission downloading a big file even with speed limitations, and when I read same file over NFS everything is ok. I have no extra hdd to reproduce the problem.

And what about wifi?
firefly@firefly:~$ cat /var/log/syslog

...
Dec 18 20:43:14 firefly kernel: [  876.079038] Error getting the SSID

Dec 18 20:43:20 firefly kernel: [  882.078423] Error getting the SSID

No kernel errors when I boot in Armbian

OK I’ve found who was requesting SSID every 3 second - conky, now turned off and this problem elimnated
but still I get messages:

[41058.513959] _tdata_psh_info_pool_deq 200: Out of tdata_disc_grp

[41058.541165] dhd_tcpdata_info_get 1092: No more free tdata_psh_info!!

google doesn’t see anything reasonable

The error message is in the WiFi driver of
drivers/net/wireless/rockchip_wlan/rkwifi/bcmdhd/dhd_ip.c:

    tdata_psh_info = _tdata_psh_info_pool_deq(tcpack_sup_mod);

#ifdef DHDTCPACK_SUP_DBG
DHD_TRACE((“%s %d: PSH INFO ENQ %d\n”,
FUNCTION, LINE, tcpack_sup_mod->psh_info_enq_num));
#endif /* DHDTCPACK_SUP_DBG */

    if (tdata_psh_info == NULL) {
            DHD_ERROR(("%s %d: No more free tdata_psh_info!!\n", __FUNCTION__, __LINE__));
            ret = BCME_ERROR;
            dhd_os_tcpackunlock(dhdp, flags);
            goto exit;
    }

and

static tdata_psh_info_t*
_tdata_psh_info_pool_deq(tcpack_sup_module_t *tcpack_sup_mod)
{
tdata_psh_info_t *tdata_psh_info = NULL;

    if (tcpack_sup_mod == NULL) {
            DHD_ERROR(("%s %d: ERROR %p\n", __FUNCTION__, __LINE__,
                    tcpack_sup_mod));
            return NULL;
    }

    tdata_psh_info = tcpack_sup_mod->tdata_psh_info_free;
    if (tdata_psh_info == NULL)
            DHD_ERROR(("%s %d: Out of tdata_disc_grp\n", __FUNCTION__, __LINE__));
    else {
            tcpack_sup_mod->tdata_psh_info_free = tdata_psh_info->next;
            tdata_psh_info->next = NULL;

#ifdef DHDTCPACK_SUP_DBG
tcpack_sup_mod->psh_info_enq_num–;
#endif /* DHDTCPACK_SUP_DBG */
}

    return tdata_psh_info;

}

Currently have no idea of what caused the problem.
