Greetings, =CE=99 have followed the guide about setting up the serial console: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ppp-and-slip.html =CE=99 have done this many times with no problems to other servers. For the first time I have a very strange problem in this particular server:= =20 After seeing some kernel messages, =CE=99 see garbage characters, the machi= ne hangs completely and only a hard reset can be done.=20 The garbage characters appear just before the uart initilization. The last messages that I can see in the serial console: =2E... atapci2: <Intel 6300ESB SATA150 controller> port 0xa800-0xa807,0xa480-0xa48= 3,0xa400-0xa407,0xa080-0xa083,0xa000-0xa00f irq 18 at device 31.2 on pci0 atapci2: [ITHREAD] ata5: <ATA channel 0> on atapci2 ata5: [ITHREAD] ata6: <ATA channel 1> on atapci2 ata6: [ITHREAD] pci0: <serial bus, SMBus> at device 31.3 (no driver attached) acpi_button0: <Power Button> on acpi0 atrtc0: <AT realtime clock> port 0x70-0x71 irq 8 on acpi0 atkbdc0: <Keyboard controller (i8042)> port 0x60,0x64 irq 1 on acpi0 atkbd0: <AT Keyboard> irq 1 on atkbdc0 kbd0 at atkbd0 atkbd0: [GIANT-LOCKED] atkbd0: [ITHREAD] =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF= =BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF= =BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD =EF=BF=BD=EF=BF=BD?=EF=BF= =BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF= =BD =EF=BF=BD=EF=BF=BD?=EF=BF=BD =EF=BF=BD=EF=BF=BD?=EF=BF=BD =EF=BF=BD=EF= =BF=BD?M=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD/=EF=BF=BD=EF=BF=BD=EF=BF=BD~= =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD/= =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD~=EF=BF=BD=EF=BF=BD=EF=BF=BDM= =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD/=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD= =EF=BF=BD~=EF=BF=BD=EF=BF=BD=EF=BF=BDM=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD= =EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF= =BF=BD{>=EF=BF=BD{>=EF=BF=BD?<=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD'=EF=BF= =BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD'=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF= =BD?<=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF= =BD=EF=BF=BD=EF=BF=BD=EF=BF=BD?u=EF=BF=BD=EF=BF=BDu=EF=BF=BD=EF=BF=BD=EF=BF= =BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD~^D =3D=3D> at this point the whole machine freezes!
