Message-ID: <alpine.LNX.2.02.1307041139490.30343@eeeadesso> Date: Thu, 4 Jul 2013 11:45:14 +0200 (CEST) From: Enrico Mioso <mrkiko.rs@...il.com> To: netdev@...r.kernel.org Subject: "Kevent 2 may have been dropped" - why? 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! -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
