Packet loss with QCA9377 (ath10k) on ASUS VivoBook E410KA

[Bandhan Pramanik]

Hello,

I'm helping someone who was having trouble with their Wi-Fi on Asus 
VivoBook E410KA. The device uses the QCA9377 Wireless Chip.

The device suffered from a single packet loss within 33 seconds while 
running a continuous ping. There might be some PCIe-level communication 
problems too.

All the relevant logs can be found here in a redacted form:

First part (ping, hostnamectl, ip addr, lspci):

Second part (cat /proc/interrupts, modinfo ath10k_pci): 
https://gist.github.com/BandhanPramanik/7eefd192c3a728d2473687a786fbbc01/raw/e77f0fa1cf35c748730df220b0057399ac78f539/miscellaneous%25202

dmesg:

We’re not sure if this is a driver issue, a firmware problem, or maybe 
something hardware-specific.

Has anyone seen something similar with this chip? Any tips on how to 
troubleshoot or fix the packet loss?

Thanks,
