I'd like to verify this git bisection result. (If the > module is loaded or you have CONFIG_USB_SERIAL=y instead of m, try to > recompile the kernel with this option turned off, for this test.) sorry for taking so long to get back. busy problematic times. the dumps and ifconfigs are a bit less 'clean' because the router serves several other computers (none of which have this issue (windows)) here's the ifconfig -a from the router. usbserial is not loaded. actually from reading the patch submission I suspected the official cause might be off... but I'm not kernel programmer all I know is where I could see the loss during tests.and I haven't been able to reproduce over dozens of reboots from this 2.6.31.1-test-00091-gfa31221 kernel. I totally forgot to do it during the dump's so I hope these are still useful I haven't rebooted this in a few weeks (the router) br-lan Link encap:Ethernet HWaddr 00:1D:7E:F8:21:66 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:60613991 errors:0 dropped:0 overruns:0 frame:0 TX packets:67849334 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2172912561 (2.0 GiB) TX bytes:3999263405 (3.7 GiB) eth0 Link encap:Ethernet HWaddr 00:1D:7E:F8:21:66 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:144116625 errors:0 dropped:0 overruns:0 frame:0 TX packets:122639966 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1986512923 (1.8 GiB) TX bytes:1548485891 (1.4 GiB) Interrupt:4 eth0.0 Link encap:Ethernet HWaddr 00:1D:7E:F8:21:66 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:57318567 errors:0 dropped:0 overruns:0 frame:0 TX packets:62317675 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3466538358 (3.2 GiB) TX bytes:2132301174 (1.9 GiB) eth0.1 Link encap:Ethernet HWaddr 00:1D:7E:F8:21:66 inet addr:68.42.198.183 Bcast:255.255.255.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:86777655 errors:0 dropped:0 overruns:0 frame:0 TX packets:60312064 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:205005516 (195.5 MiB) TX bytes:3162930981 (2.9 GiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:168 errors:0 dropped:0 overruns:0 frame:0 TX packets:168 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:19706 (19.2 KiB) TX bytes:19706 (19.2 KiB) wl0 Link encap:Ethernet HWaddr 00:1D:7E:F8:21:68 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5114480 errors:0 dropped:0 overruns:0 frame:720205 TX packets:7576790 errors:1902 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:762579947 (727.2 MiB) TX bytes:3981402458 (3.7 GiB) Interrupt:2 Base address:0x5000 this is the ifconfig -a from my desktop while experiencing the issue eth0 Link encap:Ethernet HWaddr 00:21:9B:06:4C:C9 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::221:9bff:fe06:4cc9/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3465 errors:0 dropped:0 overruns:0 frame:0 TX packets:4951 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:1467320 (1.3 Mb) TX bytes:631808 (617.0 Kb) Memory:fdfc0000-fdfe0000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:624 errors:0 dropped:0 overruns:0 frame:0 TX packets:624 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:64397 (62.8 Kb) TX bytes:64397 (62.8 Kb) -- Caleb Cushing http://xenoterracide.blogspot.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
