I just had a new crash with these symptoms, again exactly when starting 'dvdisaster'. dmesg then shows a lot of those: ahcich0: Timeout on slot 20 ahcich0: is 04000000 cs fff00007 ss fff00007 tfd 451 serr 00400000 ahcich0: port is not ready (timeout 10000ms) tfd = 00000480 repeating for multiple ports with different values, but every time with tfd = 00000480, whatever that may be. Obviously, the 10000ms timeout corresponds to the 10 seconds period of the HDD LED going on and off when the machine is in that state. I didn't test this yet with msi disabled: % sysctl -a | grep msi hw.bce.msi_enable: 1 hw.pci.honor_msi_blacklist: 1 hw.pci.enable_msix: 1 hw.pci.enable_msi: 1 hw.drm.msi: 1 Thanks, -cpghost. -- Cordula's Web. http://www.cordula.ws/ _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
