--- Comment #15 from Leo Bicknell <[email protected]> --- Ah, ok, so: Test #1: Drop to loader prompt. "copy_staging enable". "enable-module xxx" for each of the modules. Boot hangs after probing picb6. Test #2: Drop to loader prompt. "copy_staging enable". Run enable-module for the ones that end up auto-loaded anyway, which is: ichsmb, ig4, ucom, wmt, acpi_wmi, and pchtherm Kernel hangs after probing pci6b. This is really interesting to me, manually telling them to load doesn't work, but letting the kernel auto-load them does work. Test #3: Drop to loader prompt. "copy_staging enable". Run enable-module for ichsmb, ig4, ucom. Kernel hangs after probing pci6b. Test #4: Drop to loader prompt. "copy_staging enable". Run enable-module for wmt, acpi_wmi, pchtherm. Booted into multi-user mode successfully. Test #5: Drop to loader prompt. "copy_staging enable". Run enable-module for ichsmb. Booted into multi-user mode successfully. Test #6: Drop to loader prompt. "copy_staging enable". Run enable-module for ig4. Kernel hangs after probing pci6b. Test #7: Drop to loader prompt. "copy_staging enable". Run enable-module for ucom. Booted into multi-user mode successfully. Test #8: Drop to loader prompt. "copy_staging enable". Run enable-module for ichsmb, ucom, wmt, acpi_wmi, pchtherm. Booted into multi-user mode successfully. That may narrow down the problem module to "ig4". Curiously that shows as loaded in kldstat output if I don't have it in loader.conf or manually load it; it's being auto-loaded somewhere. And the auto-load works fine, it's just when manually loaded or in loader.conf that it hangs. -- You are receiving this mail because: You are the assignee for the bug.
