Date: Wed, 11 Jan 2006 13:15:07 -0800 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: [Bugme-new] [Bug 5869] New: After pon: Kernel BUG at net/core/skbuff.c:94 - seems to disable keyboard http://bugzilla.kernel.org/show_bug.cgi?id=5869 Summary: After pon: Kernel BUG at net/core/skbuff.c:94 - seems to disable keyboard Kernel Version: 2.6.15 Status: NEW Severity: high Owner: [EMAIL PROTECTED] Submitter: [EMAIL PROTECTED] Most recent kernel where this bug did not occur: 2.6.9 (did not test any later) Distribution: 64bit Debian Hardware Environment: AMD64, PS/2 keyboard, 3COM US Robotics modem Software Environment: dist-upgrade on 2006-01-10 Problem Description: First: I am not really familiar with kernel bug reporting. So if you have questions, ask me at wol (at) kulmbach (dot) net I did a dist-upgrade and a kernel-update from 2.6.9 to 2.6.15. Afterwards: When I do a pon, a bug report (attached below) is filed to the logs. The behaviour I observe is: I seem to get no connection, although it seems to login at my provider. AND: My keyboard stops working while it dials. So after the first pon, I have no keyboard until rebooting. After several seconds, the modem shuts up. Steps to reproduce: Log: Jan 11 21:22:02 eiswiese pppd[2372]: pppd 2.4.4b1 started by root, uid 0 Jan 11 21:22:03 eiswiese chat[2373]: abort on (BUSY) Jan 11 21:22:03 eiswiese chat[2373]: abort on (NO CARRIER) Jan 11 21:22:03 eiswiese chat[2373]: abort on (VOICE) Jan 11 21:22:03 eiswiese chat[2373]: abort on (NO DIALTONE) Jan 11 21:22:03 eiswiese chat[2373]: abort on (NO DIAL TONE) Jan 11 21:22:03 eiswiese chat[2373]: abort on (NO ANSWER) Jan 11 21:22:03 eiswiese chat[2373]: abort on (DELAYED) Jan 11 21:22:03 eiswiese chat[2373]: send (AT&F1X3^M) Jan 11 21:22:03 eiswiese chat[2373]: expect (OK) Jan 11 21:22:03 eiswiese chat[2373]: AT&F1X3^M^M Jan 11 21:22:03 eiswiese chat[2373]: OK Jan 11 21:22:03 eiswiese chat[2373]: -- got it Jan 11 21:22:03 eiswiese chat[2373]: send (ATDT019102244^M) Jan 11 21:22:04 eiswiese chat[2373]: expect (CONNECT) Jan 11 21:22:04 eiswiese chat[2373]: ^M Jan 11 21:22:29 eiswiese chat[2373]: ATDT019102244^M^M Jan 11 21:22:29 eiswiese chat[2373]: CONNECT Jan 11 21:22:29 eiswiese chat[2373]: -- got it Jan 11 21:22:29 eiswiese chat[2373]: send (\d) Jan 11 21:22:30 eiswiese pppd[2372]: Serial connection established.
