Looks like driver interrupts, on cpu #0, and at IPL 4. What interrupts are bound to cpu 0 / IPL 4, on your machine? This information is printed by echo ::interrupts | mdb -k Does the command "intrstat" show lots of interrupts / lots of cpu time usage? -- This message posted from opensolaris.org _______________________________________________ opensolaris-help mailing list opensolaris-help@opensolaris.org
