DL 6:26pm 24:09,84 [bktr0_msp34xx] You can also see using systat that bktr0_msp34xx is still active after closing xawtv. Further info: bktr0: <BrookTree 878> mem 0xdddfe000-0xdddfefff irq 19 at device 11.0 on pci0 bktr0: Hauppauge Model 44804 C108 bktr0: Detected a MSP34255?-?31 at 0x80 bktr0: Hauppauge WinCast/TV, Philips PAL I tuner, msp3400c stereo. device bktr options OVERRIDE_CARD=2 options OVERRIDE_MSP=2 options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL options BKTR_NEW_MSP34XX_DRIVER options BKTR_GPIO_ACCESS I've seen this behavior on more than one PC and also on earlier FreeBSD versions. >How-To-Repeat: You need xawtv and a WinTV card. 1) start xawtv 2) exit xawtv 3) take a look at "ps aux" and "systat" output >Fix: n/a >Release-Note: >Audit-Trail: >Unformatted:
