>Description:
After few minutes of heavy networking, kernel or double kernel panic happens.
Hardware:
Soltek DRV5 VIA KT333 motherboard, AMD Athlon XP 1600+ CPU, 256MB DDR RAM, RealTek 8139C and Compaq NC3121 (Intel SB82558B) NICs. Only one NIC (fxp1) is used.
Machine works *without* problems under 4.6.1- (I've noted this problem some time ago and downgraded machine to RELEASE) and 4.6.2-RELEASE. Kernel panic occurs only when I switch to 4.6-STABLE.
I've compiled a GENERIC kernel with debugging option and with make defaults. Here are results:
1st crash:

>How-To-Repeat:
Install FreeBSD 4.6-STABLE on machine as described above and try to use it harder (transferring big files) over Compaq/Intel NIC.
>Fix:
Unknown.
Work-around: downgrade to 4.6.2-RELEASE or use other non-fxp NIC.

I've switched all network traffic from fxp1 to rl0 NIC and transferred ~3GB of data without kernel panic. So the bug seemd to be related with fxp1.
I suppose it is not a hardware (Compaq/Intel NIC) fault, because there are no problems when I downgrade to 4.6.2-RELEASE.
