I started noticed this a couple of days ago, especially when when I'm doing a cvsup. I was originally running with -current from the end of July, but updated my -current box to late 8/22. What else should I be looking at? There are no error messages in /var/log/messages before the panic. #0 boot (howto=260) at ../../kern/kern_shutdown.c:281 #1 0xc0154f49 in panic (fmt=0xc0276844 "m_copym") at ../../kern/kern_shutdown.c:529 #2 0xc016d16a in m_copym (m=0xc0abcf80, off0=5736, len=342, wait=1) at ../../kern/uipc_mbuf.c:446 #3 0xc01a6a6b in tcp_output (tp=0xcbe2cba0) at ../../netinet/tcp_output.c:511 #4 0xc01a7ba9 in tcp_fasttimo () at ../../netinet/tcp_timer.c:106 #5 0xc016c94f in pffasttimo (arg=0x0) at ../../kern/uipc_domain.c:230 #6 0xc015966a in softclock () at ../../kern/kern_timeout.c:132 #7 0xc022e15e in doreti_swi () #8 0xc01fb409 in drain_output (vp=0xcbef19c0, islocked=1) at ../../ufs/ffs/ffs_softdep.c:4451 #9 0xc01fa3da in softdep_fsync_mountdev (vp=0xcbef19c0) at ../../ufs/ffs/ffs_softdep.c:3725 #10 0xc01fe7f6 in ffs_fsync (ap=0xcd3dbd1c) at ../../ufs/ffs/ffs_vnops.c:135 #11 0xc01fd05e in ffs_sync (mp=0xc0ec9000, waitfor=2, cred=0xc0a64880, p=0xc02e0ea0) at vnode_if.h:499 #12 0xc017e43f in sync (p=0xc02e0ea0, uap=0x0) at ../../kern/vfs_syscalls.c:545 #13 0xc015494b in boot (howto=256) at ../../kern/kern_shutdown.c:198 #14 0xc0154f49 in panic (fmt=0xc0276844 "m_copym") at ../../kern/kern_shutdown.c:529 #15 0xc016d16a in m_copym (m=0xc0abcf80, off0=5736, len=342, wait=1) at ../../kern/uipc_mbuf.c:446 #16 0xc01a6a6b in tcp_output (tp=0xcbe2cba0) at ../../netinet/tcp_output.c:511 #17 0xc01a5cb2 in tcp_input (m=0xc0abcd80, iphlen=20) at ../../netinet/tcp_input.c:1792 #18 0xc01a1538 in ip_input (m=0xc0abcd80) at ../../netinet/ip_input.c:679 #19 0xc01a1597 in ipintr () at ../../netinet/ip_input.c:706 #20 0xc022e1a5 in swi_net_next () #21 0xc024ecc1 in intr_mux (arg=0xc0a5d560) at ../../i386/isa/intr_machdep.c:549 #22 0x807b5d5 in ??
