Cyrus recently identified a dead-lock in the APIC_IO version. The symptom is a complete freeze of the system while doing heavy IO. Are you using the APIC_IO version? When you say "crash", do you mean spontanious reboot, panic, or freeze? Earlier today I commited a "bandaid" that should help with this problem. Did you get the version of mpapic.h that has "#define APICIPI_BANDAID" in it? -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
