[Bug 625265] Re: rtl8187: spontaneously disassociates
I omitted to remove the needs-upstream-testing tag, I'm not that familiar with all the LP functions. I noted in the bug I that tested with linux-image-2.6.35-020635rc1-generic. That has the same problems. I tested again, with linux-image-2.6.32-0206322109-generic_2.6.32-0206322109.201008271507_i386.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.21.9-lucid/ $ uname -a Linux ubuntu 2.6.32-0206322109-generic #201008271507 SMP Fri Aug 27 16:10:51 UTC 2010 i686 GNU/Linux I tried this for a couple of days. The interface falls over after a few minutes to a few hours. Here's what dmesg says about the insertion (hot-plug) of the device with that kernel: [ 1212.644016] usb 1-2: new high speed USB device using ehci_hcd and address 4 [ 1212.783305] usb 1-2: configuration #1 chosen from 1 choice [ 1213.131068] phy1: Selected rate control algorithm 'minstrel' [ 1213.132204] phy1: hwaddr 00:1e:2a:d0:49:db, RTL8187BvE V0 + rtl8225z2, rfkill mask 2 [ 1213.153627] rtl8187: Customer ID is 0x00 [ 1213.155570] Registered led device: rtl8187-phy1::tx [ 1213.156396] Registered led device: rtl8187-phy1::rx [ 1213.157119] rtl8187: wireless switch is on [ 1213.157397] usbcore: registered new interface driver rtl8187 [ 1213.197568] udev: renamed network interface wlan0 to wlan1 [ 1217.014780] ADDRCONF(NETDEV_UP): wlan1: link is not ready [ 1219.117222] wlan1: direct probe to AP 00:04:ed:b9:1c:d7 (try 1) [ 1219.120218] wlan1: direct probe responded [ 1219.120222] wlan1: authenticate with AP 00:04:ed:b9:1c:d7 (try 1) [ 1219.121967] wlan1: authenticated [ 1219.121984] wlan1: associate with AP 00:04:ed:b9:1c:d7 (try 1) [ 1219.124965] wlan1: RX AssocResp from 00:04:ed:b9:1c:d7 (capab=0x431 status=0 aid=4) [ 1219.124968] wlan1: associated [ 1219.130471] ADDRCONF(NETDEV_CHANGE): wlan1: link becomes ready And then I get only these items in dmesg: [ 1986.324027] [drm] nouveau :01:00.0: Setting dpms mode 1 on vga encoder (output 1) [ 7582.500014] No probe response from AP 00:04:ed:b9:1c:d7 after 500ms, disconnecting.

Not clear why the difference is so large, they are less than a metre apart, (not too close, in case of interference). The pci card antenna is connected fine, the system case is not metal (Dell). I shut down this interface and started another test with just the netgear. It failed in exactly the same way as before. here's dmesg for when the interface comes up: [90153.178570] ADDRCONF(NETDEV_UP): wlan1: link is not ready [90155.261318] wlan1: direct probe to AP 00:04:ed:b9:1c:d7 (try 1) [90155.263699] wlan1: direct probe responded [90155.263703] wlan1: authenticate with AP 00:04:ed:b9:1c:d7 (try 1) [90155.267184] wlan1: authenticated [90155.267201] wlan1: associate with AP 00:04:ed:b9:1c:d7 (try 1) [90155.269187] wlan1: RX AssocResp from 00:04:ed:b9:1c:d7 (capab=0x431 status=0 aid=4) [90155.269191] wlan1: associated [90155.274688] ADDRCONF(NETDEV_CHANGE): wlan1: link becomes ready later I find the interface in this state: wlan1 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:F43E-D0B4-6B Power Management:off and this in dmesg: [90767.052019] [drm] nouveau :01:00.0: Setting dpms mode 1 on vga encoder (output 1) [91104.500017] No probe response from AP 00:04:ed:b9:1c:d7 after 500ms, disconnecting. Reporting on this is being complicated by something strange happening with logging using this kernel. dmesg is updating, but I am not getting kernel messages in the other logs. Every time I restart rsyslogd I get in /var/log/kern.log: Sep 17 21:17:11 ubuntu kernel: imklog: Cannot read proc file system, 1. I see syslog messages for cron jobs etc but not kernel-related things. Not sure if there is anything I can do about this, please advise. ** Tags removed: needs-upstream-testing -- rtl8187: spontaneously disassociates https://bugs.launchpad.net/bugs/625265 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 625265] Re: rtl8187: spontaneously disassociates
Hi Vince, If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.] ** Tags added: kj-triage ** Changed in: linux (Ubuntu) Status: New = Incomplete -- rtl8187: spontaneously disassociates https://bugs.launchpad.net/bugs/625265 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 625265] Re: rtl8187: spontaneously disassociates
Went back to 2.6.32-22-generic, since that fixed other issues (LP:459732). I installed linux-image-2.6.32-22-generic (version 2.6.32-22.36) and linux-backports-modules-wireless-2.6.32-33-generic (version 2.6.32-22.13) and rebooted, then selected this kernel from the grub list. The same failure occurs, with the same error message. However I don't see the message about the bogus regulatory domain on this kernel. So something has changed there. I haven't messed about with 'wireless-crda', the version installed is 1.12, installed 2010-04-16. Here's the timeline of associations and disassociations with 2.6.32-22-generic: system boot Aug 31 22:43:03 ubuntu kernel: [ 25.199388] wlan1: associated cron job restarts interface Sep 1 00:55:01 ubuntu kernel: [ 7943.304273] wlan1: deauthenticating from 00:04:ed:00:00:00 by local choice (reason=3) ...
