Hello,
On recently compiled kernels, I often get panics which seemed to be =
interrupt related. Among other things, almost all of them claims that =
"Kernel trap 30", which seemd to be strange.=20
The kernel I am currently running, namely,
FreeBSD servers.frontfree.net 5.1-CURRENT FreeBSD 5.1-CURRENT #5: Sat =
Oct 25 22:27:05 CST 2003 =
delphij@servers.frontfree.net:/usr/obj/usr/src/sys/SERVERS i386
seemed to be ok, however, when I am trying the new kernels (you see, 14 =
compile and run attempts:), it exhibits incredible instablity.
FreeBSD 5.1-CURRENT #19: Wed Nov 12 12:17:28 CST 2003
delphij@servers.frontfree.net:/usr/obj/usr/src/sys/SERVERS
Here is one of the crashdumps I caught. The machine was configured with =
a UP kernel, with DEVICE_POLLING enabled. There are two networking =
adapters attached to it, a fxp and a dc, and the machine itself act as a =
NAT gateway. The network load is not very heavy. If you think the =
backtrace helpful, or need any more information, please write me and I =
will try everything I can to help.
