Hi all guys! Please CC me - as I'm not subscribed to this list!
After some hours of usage of qmi-wwan or huawei_cdc_ncm drivers, I see that
message trigger, in file drivers/net/usb/usbnet.c at line 427.
In my dmesg, it looks like:
[183782.743539] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.743909] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.743998] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744083] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744166] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744252] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744335] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744421] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744504] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
[183782.744586] huawei_cdc_ncm 3-2:1.1 wwan0: kevent 2 may have been dropped
And the same happens with qmi_wwan.
I understand this is related to kernel workqueue mechanism - but don't
understand exactly why it triggers, and if we can do something.
thank you!
