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!!

Copy the code

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.

2. 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

Copy the code

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

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
[41058.513978] dhd_tcpdata_info_get 1092: No more free tdata_psh_info!!

Copy the code

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.
