When I tried to print (using lpr) a conf file, the system crashed with a panic in lockmgr. I will crash every time I try to print. For the most part the system is stable, except for lpr. Here is the dump from the panic and a kernel trace. panic: lockmgr: pid 439, not exlusive lock holder 322 unlocking mp_lock = 00000001; cpuid = 0 lapic.id = 00000000 Debugger(...) at Debugger+037 panic(...) at panic+0xa8 lockmgr(...) at lockmgr+0x2bc brelse(...) at brelse+0x636 lptclose(...) at lptclose+0xaa spec_close(...) at spec_close+0x90 ufsspec_close(...) at ufsspec_close+0x3e ufs_vnoperatespec(...) at ufs_vnoperatespec+0x15 vn_close(...) at vn_close+0x40 vn_closefile(...) at vn_closefile+0x20 fdrop(...) at fdrop+0xb9 closef(...) at closef+0x9b fdfree(...) at fdfree+0x30 exit1(...) at exit1+0x175 exit1(... at exit1 syscall(...) at syscall+0x149 Xint0x80_syscall(...) at Xint0x80_syscall+0x31 By the way, this is a SMP box with dual PII-400 running on a SuperMicro P6DBE MB with SCSI disks.
