Well, here it is (via serial console): RockRidge Extension panic: sleeping without a mutex at line 144 in file /usr/src/sys/kern/kern_synch.c cpuid = 0; Debugger("panic") Stopped at Debugger+0x46: xchgl %ebx,in_Debugger.0 db> tr Debugger(c07bf6c1) at Debugger+0x46 __panic(c07bfedf,90,c07bfeb7,653,c08aee6c) at __panic+0x13d msleep(c0875ae0,0,1a0,c07d3d27,0) at msleep+0xc2 random_read(c087b3dc,d7618c88,20000,c07fc6e0,74) at random_read+0x41 spec_read(d7618bec,d7618c38,c063b84d,d7618bec,d7618c88) at spec_read+0x12c spec_vnoperate(d7618bec) at spec_vnoperate+0x13 vn_read(c47d9330,d7618c88,c1d19600,0,c464b690) at vn_read+0x185 dofileread(c464b690,c47d9330,4,bfbfe4dc,74) at dofileread+0xb0 read(c464b690,d7618d14,3,1,296) at read+0x3b syscall(2f,2f,2f,855b000,3e) at syscall+0x217 Xint0x80_syscall() at Xint0x80_syscall+0x1d --- syscall (3, FreeBSD ELF32, read), eip = 0x82776ab, esp = 0xbfbfe49c, ebp = 0xbfbfe568 --- db> Combination to reproduce: - boot from fixit CD - select fixit, live CD - Enter to confirm mount Any other info we need?
