Eeek! page_mapcount(page) went negative! (-1)

kernel BUG at mm/rmap.c:725!

Fixing recursive fault but reboot is needed!

does segfault, nefunguje:

mencoder -tv buffersize=200:input=1:freq=603.15:fps=18:normid=8:mjpeg:decimation=1:adevice=/dev/dsp:outfmt=yv12 tv:// -ovc copy -lavcopts acodec=mp2 -oac lavc -o /suplik/output.avi

works, funguje:

mencoder -tv buffersize=200:input=1:freq=603.15:fps=20:normid=8:adevice=/dev/dsp:outfmt=yuy2:width=768:height=576 tv:// -ovc copy -lavcopts acodec=mp2 -oac lavc -o /raid0/output.avi

spustit mencoder

ihned immediate ctrl+c

zkontrlovat check

 Current format: BGR24
 

spustit mencoder podruhe second time

ihned immediate ctrl+c

zkontrolovat check

 Current format: BGR24
 

nesmi tam byt neco yvu420 nebo podobne protoze bttv si rekne o yuyv a ATI TV Wonder VE s bt878 chipem vrati neco jineho a to je videt pri druhem spusteni co bylo current format minule. videobuffer mencoderu je pak kratsi a kdyz se zacne plnit, tak se obcas neco prepise, takze kdyz nekdo dimenzuje nahravani na 3-1%idle cpu a nekde se neco probudi nebo je treba uklidit, tak se zacnou dit veci.
