--Sig_S6fYkIbOHoXcPz8jCY5Ltrh Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable As described in: http://lists.freebsd.org/pipermail/freebsd-stable/2006-June/026554.html I'm currently experiencing strange hangs or crashes with a FreeBSD RELENG_6 system running Tor. In case of the Tor related hangs the serial console becomes unresponsive together with the rest of the system, therefore I can't get into ddb to provide useful information about the cause of the problem. sio0 is attached on acpi0 and while I have no reason to believe that acpi0 is part of the problem, I'd like to make sure and use sio0 without it. Disabling acpi all together with hint.acpi.0.disabled works, but it also renders fxp0 useless. It comes up but only generates timeout messages. acpi(4) lists several ways to disable acpi sub-systems, but apparently I don't get the syntax right. The system's device configuration is: [fk@tor ~]$ devinfo=20 nexus0 npx0 acpi0 cpu0 acpi_throttle0 cpufreq0 acpi_button0 acpi_sysresource0 pcib0 pci0 agp0 pcib1 pci1 pcib2 pci2 fxp0 miibus0 inphy0 fxp1 miibus1 inphy1 isab0 isa0 pmtimer0 sc0 vga0 atkbdc0 atkbd0 orm0 atapci0 ata0 ad0 ata1 pci_link0 pci_link1 pci_link2 pci_link3 pci_link4 pci_link5 pci_link6 pci_link7 acpi_sysresource1 atpic0 atdma0 attimer0 attimer1 npxisa0 sio0 sio1 ppc0 ppbus0 plip0 lpt0 ppi0 acpi_tz0 acpi_timer0 Could someone please tell me how to stop acpi0 from grabbing sio0, without affecting fxp0?
