Sure I will do my very best. First of all: Hang of the webcam, kernel hang I did not reproduce up to now:
2.6.0-test1-ac1 kernel: set the pio mode of the hard disk to 0 turned on traces of pwc Jul 29 22:05:56 (none) kernel: pwc VIDIOCSYNC: frame ready. Jul 29 22:05:56 (none) kernel: pwc VIDIOCMCAPTURE: 320x240, frame 0, format 15 Jul 29 22:05:56 (none) kernel: pwc VIDIOCMCAPTURE done. Jul 29 22:05:56 (none) kernel: pwc VIDIOCSYNC called (0). Jul 29 22:05:56 (none) kernel: pwc Frame buffer underflow (114618 bytes); discarded. Jul 29 22:05:56 (none) kernel: pwc VIDIOCSYNC: frame ready. Jul 29 22:05:56 (none) kernel: pwc VIDIOCSYNC called (1). Jul 29 22:05:56 (none) kernel: pwc VIDIOCSYNC: frame ready. at this point my Java Media Framework says, that it could not initialize the capture device anymore. I loaded the system with cat /dev/hdb >/dev/null to produce this problem. As far as I could see, this is the first time in the sys log, VIDIOCSYNC is called after a frame ready immediatly. I hope this helps, I am sending kernel data later Detlef ----- Original Message ----- From: "Nemosoft Unv." <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, July 28, 2003 10:12 PM Subject: Re: [linux-usb-devel] pwc stops if the system is loaded > Hello, > > On Monday 28 July 2003 08:03, Detlef Schmicker \(Siebertz Electronic GmbH\) > wrote: > > Hello Oliver, > > > > I have no simple way to reproduce it at the moment, but I observed both: > > Hang of the webcam (one observation after 3 days of working) > > Hang of the kernel (one observation after 2 days of working) > > > > This observation is done with my advantech SOM on the original develoment > > board, > > any wireing problems I discussed earlier should be not present.
