From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2.1) Gecko/20010901 Description of problem: Running RHL 7.2 on Dell Latitude CPi 266 with 160MB ram. Wireless networking with Lucent/Orinoco silver with Residential Gateway 1000. Networking works fine until I run tcpdump for a short while. The failure is not immediate, but takes less than 1 minute to manifest. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.In one window, run "ping otherhost" 2.In another window, run "tcpdump icmp" 3.For a little while, both windows show appropriate output. Then, without cause and without any error messages what-so-ever, the laptop cannot see the rest of the network. No ping, no nothing, no error messages (at least none that I saw) The system is up2date, i.e. running kernel-2.4.9-13, and registered in RHN and running updated RPMs. Actual Results: In order to bring the laptop online again, I had to run: service pcmcia restart Expected Results: I wish using tcpdump wouldn't knock me off the air. :-) Additional info:
Apologies for the lack of response. This is probably a bug with the kernel drivers. Please reopen if this happens on a more current distribution.
