https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268393 --- Comment #27 from John Grafton <firstname.lastname@example.org> --- Created attachment 241040 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=241040&action=edit lock hdac during init I have a theory that an interrupt is being triggered before the dma memory is allocated correctly for hdac2. I've included a patch that locks the hdac driver initialization sequence which should block any interrupts (that call hdac_rirb_flush) before the initialization completes. This patch is just for testing. You should see some WITNESS debugger complaints about bouncing off the lock. If the system actually boots and doesn't crash, will you send the dmesg? -- You are receiving this mail because: You are the assignee for the bug.
