The removed DEFINE_PCI_DEVICE_TABLE in Linux 4.8 may cause the compiling error.

Hi there,
I found this driver not stable in 4.11.6-3-ARCH.
This the error log.

[  109.279075] ieee80211 phy0: rt2x00lib_rxdone: Error - Wrong frame size 0 max 3840
[15443.493294] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0   
Please file bug report to http://rt2x00.serialmonkey.com

Is there anything I can provide?

Thank you.

when in an environment like college campus (same SSID with multiple routers(Access points)) the WIFI keeps dropping and finally it stops reconnecting.
I'm very new to Linux, kindly let me know if you require the logs and how to get them.

Thank you,
VK

First, thanks for the driver.
My system is Archlinux 4.0.5 Linux.
Driver crash every 15 seconds

If you can update for the new kernel 4.9, it could be interesting.
Thanks U
Gerome L.

Seems like your advice is making things worst.
At least I tried to apply it to kuba-moo,
Will try again & tell,
As you might have guess I have the hardware.

Do you have any input for a better understanding how it should work,
I kown C quite well, but no knownledge of kernel dev, call back functions, all these things I guess to be involved there.

If I can somehow help please tell how.

For the time being I stay with my current driver.

Thks 4 ur attention.

How about doing pull request to kuba-moo's repository with your patch?
It seems that kuba-moo is working with Linux Wireless(at kernel.org), so merging every efforts to his repository would be good.

Sorry for my poor English, and thank you for your efforts.

The issue kuba-moo/mt7630e#19 seems to affect this variant of the driver as well.

Sometimes the following error is reported to the system log at boot time or when I try to unload mt7630e:

When it happens at boot, the system hangs and becomes unusable until reboot (even no reaction to the magic sysrq).

If I blacklist the driver at boot (modprobe.blacklist=mt7630e), the problem have not shown up so far.

OS: ROSA Linux R6 x86_64
Kernel: 4.1.15
WiFi adapter: pci:14c3-7630-103c-197c (MT7630e 802.11bgn Wireless Network Adapter)

More details and the logs: http://hw.rosalinux.ru/index.php?probe=050ffb018c
I had to reboot the system before collecting them, so the full system log of the previous problematic boot is http://hw.rosalinux.ru/index.php?probe=050ffb018c&log=journalctl.1

Any ideas?

Whenever i want to install it with "yaourt -S mt7630-pcie-wifi-dkms", I am getting this kind of error, Can you help me to solve this?
