[-- Attachment #1 --] Hello, I managed to get the following printed on a serial console while shutting down XFree86 today: Sleeping on "itrmh" with the following non-sleepable locks held: exclusive sleep mutex drm device r = 0 (0x6505f464) locked @ dev/drm/drm_irq.h:192 Stack backtrace: backtrace(607dd224,b00c894c,1,6599e6e0,65945d20) at 0x60564407 witness_warn(5,64faf380,60735d8f,60732f57,15a) at 0x605893f3 msleep(65777b40,64faf380,a0,60732f57,0) at 0x6056b98a ithread_remove_handler(65777b40,b00c89bc,606e4ad1,65777b40,b00c89e4) at 0x6054d695 I had DRM_DEBUG turned on and a console actively logging at the time, so I was able to produce a full trace with the DRM_DEBUG messages before and after. I have attached the file to this email. My kernel is fairly stock, with amr, nge, smp and DRM_DEBUG enabled. I can make my config file available as well as the full hardware specifications for the machine that this was found on. Google turned up something similar from last December, involving the same line of code, but it was a LOR. That report can be found here: http://lists.freebsd.org/pipermail/freebsd-current/2003-December/015540.html Any ideas?
