Hi Bill, CC to -stable I have a PC with an onboard realtek 8139 network card. It all worked great with 3.3-RELEASE but today I CVSuped and made world, and now the machine hangs and panics frequently. I can hang the machine just by ftping files from another site. I can panic the machine by using the ttcp network bandwidth tool in one screen, and running 'netstat 1' in another screen. When the panic happens, the kernel trace is small_i586_bcopy ip_input ipintr swi_net_next I took another machine running 3.3-stable (CVSup about a week ago). I removed its 10 Meg 3COM network card and added a RealTek 8139 card. It then had the same behavious - hanging whenever I started streaming any data over the network. I replaced the network card with a Linksys v2 card (using the MX driver) and the machine works correctly. So, I assumed the recent RealTek driver commit to -stable was at fault. However, I reverted if_rl.c and if_rlreg.h back to the old 3.3-Release versions and the panics still happen. So I assume the problem is elsewhere in the kernel, perhaps in the general IP code (netinet) or in the memory management (as it was a i586_bcopy which failed) Any ideas?
