(i discovered it when i tried to run openvpn). so i guess it may be the tap driver on sparc64. i can provice kernel core and offer my help. i wrote to the sparc64 mailinglist before but now i guess its better off here. regards, Michael Ortmann == how to reproduce the kernel panic == # cat /dev/zero >/dev/tap0 tap0: Ethernet address: 00:bd:00:02:10:00 panic: trap: memory address not aligned cpuid = 0 KDB: enter: panic [thread 449 tid 100044] Stopped at kdb_enter+0x3c: ta %xcc, 1 == uname -a = FreeBSD server5.q-fin 6.1-STABLE FreeBSD 6.1-STABLE #0: Sun May 28 01:53:54 CEST 2006 root@server5.q-fin:/usr/obj/usr/src/sys/SERVER5 sparc64 == kernel conf == machine sparc64 cpu SUN4U ident SERVER5 # To statically compile in device wiring instead of /boot/device.hints #hints "GENERIC.hints" # Default places to look for devices. makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols # Platforms supported # At this time all platforms are supported, as-is. #options SCHED_ULE # ULE scheduler options SCHED_4BSD # 4BSD scheduler #options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options INET6 # IPv6 communications protocols options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories #options MD_ROOT # MD is a potential root device #options NFSCLIENT # Network Filesystem Client #options NFSSERVER # Network Filesystem Server #options NFS_ROOT # NFS usable as /, requires NFSCLIENT #options MSDOSFS # MSDOS Filesystem options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework options GEOM_GPT # GUID Partition Tables. options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD5 # Compatible with FreeBSD5 options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI options KTRACE # ktrace(1) support options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options AHC_REG_PRETTY_PRINT # Print register bitfields in debug # output.
