Hello, [long message] I'm chasing strange freezes on my work PC, with a recent -Current (5.2-SNAP from 01/30). The machine is NEC PeeCee, using a Gigabyte MB, a SIS chipset and a P4-1,8GHz (dmesg to follow). The kernel is just GENERIC, with all debugging options commented out. sometimes (still, around once a day), when the machine starts swapping, it just freezes (it's possible sometimes to switch to a text virtual console and see the system messages), and it may unfreeze (or not). As the BIOS enables ACPI, it's even possible to shutdown gracefully from the power button. I have tried to start with all "defensive" options in /boot/loader.conf : hint.acpi.0.disabled=1 loader.acpi_disabled_by_user=1 hw.ata.ata_dma=0 hw.ata.atapi_dma=0 hw.ata.wc=0 hint.apic.0.disabled=1 and the freezes still happen. I will try to swap the disk (I did not see any ATA error message, like when the driver cannot read one disk sector - SMART is enabled on this disk, and the BIOS does not see any SMART error count) I have added a second (PCI) graphics card to the AGP board, and I'v setup the BIOS to use the PCI board as the console, the AGP board is only declared in /etc/X11/XF86Config. I wanted to see the vty0 messages while being under X11, but it seems as if the switch to X11 freezes the vty0, and the display is not refreshed (for example, if I leave a "top" in vty0, the display stays frozen with the last display). So [at long last] : is there a way to still have the display of vty0 refreshed on the PCI board, while X11 is displayed on the AGP board ? I suspect the keyboard is the blocking factor here (being exclusively attached to vty0 or X11) ? in the meantime, I'll try to keep an eye on xconsole, hoping all messages end up in the window. TfH
