Keyboard input is obviously active, and the console driver will let me switch virtual ttys, but no user processes seem to be getting any cpu. There's no tape drive involved in freezing the system, just disk activity across multiple devices on the controller. In particular, I've got: at scbus0 target 0 lun 0 (pass0,da0) at scbus0 target 1 lun 0 (pass1,da1) attached to: port 0xe800-0xe8ff mem 0xfebff000-0xfebfffff irq 10 at device 14.0 on pci0 I can get it to freeze reliably - meaning every time I tried to start X - on a kernel supped earlier today, wherease the one from June 24th has no problems. I've got a debugging kernel built, but don't know if I'll have time to do any work on this in the next two weeks. I should be dealing with email, though. James, you might report your hardware configuration as well.
