Subject: PROBLEM: heavy network traffic triggers system crash

1. Summary: heavy network traffic triggers "recvmsg bug" and system crash

2. Have being running Ubuntu (9.04 to 9.10) on Toshiba Satellite
L40-139 laptop. Heavy network traffic systematically triggers a crash
(either kernel panic or segmentation fault). Among applications that
have triggered system crash are: firefox (all versions since 3.2.3);
system update manager, a Java-based application downloading via
http/ftp. Usually the problem appears while downloading at speed of
150kBytes/s or more within  20-30 min. Just before the moment of
crash, tons of messages like:
Feb  3 02:30:04 kovalev-home kernel: [35474.511460] recvmsg bug:
copied BFA5DAF9 seq BFA5E0A1
fill up system logs (preceeded with application warning).
The problem has been observed first with kernel 2.6.28-13 and persists
through 2.6.31-19, all have been installed from official Ubuntu
repositories. Network connection is via Atheros AR5007eg wireless
(reported as AR5001 by ath5k), with several different routers and
providers. Since Windows Vista had never crashed by similar network
traffic on this machine, this doesn't look like a hardware fault.

Examples of warning right before crash (syslog):
