I have replaced fxp0 and fxp1 NICs with 3Com network cards=20
Now I have xl0 utilizing IRQ 10 and xl1 and xl2 sharing IRQ 11
After this "fxp{0,1} device timeout" messages changed to "xl{1,2} watchdog=
=20
timeout". xl0 still works fine. Again, xl1 and xl2 can be brought back to=
=20
life by doing ifconfig xl{1,2} down and ifconfig xl{1,2} up.
=46rom this I guess that the problem is not related to fxp or xl drivers, b=
ut to=20
the kernel interrupt management system. It seems that on SMP systems IRQ=20
sharing may cause some of the interrupts to be lost.
