Hi, while investigating the QAM_128-issue with the stv0297-driver for the Cablestar (which is not the same as the one in dvb-kernel CVS, yet), I fixed it, not by increasing the timeout, but by disabling the corner-detection for QAM_128 and higher. Could all of you, who had the problems with QAM_128, please try the attached patch to an unmodified stv0297 and report any successes or problems? Thanks in advance, Patrick. -- Mail: patrick.boettcher@xxxxxxx WWW: http://www.wi-bw.tfh-wildau.de/~pboettch/ -------------- next part -------------- Index: linux/drivers/media/dvb/frontends/stv0297.c =================================================================== RCS file: /cvs/linuxtv/dvb-kernel/linux/drivers/media/dvb/frontends/stv0297.c,v retrieving revision 1.22 diff -u -3 -p -r1.22 stv0297.c --- linux/drivers/media/dvb/frontends/stv0297.c 5 Apr 2005 00:30:39 -0000 1.22 +++ linux/drivers/media/dvb/frontends/stv0297.c 17 Jun 2005 07:24:26 -0000 @@ -606,7 +606,13 @@ static int stv0297_set_frontend(struct d stv0297_set_inversion(state, inversion); /* kick off lock */ - stv0297_writereg_mask(state, 0x88, 0x08, 0x08); + /* Disable corner detection for higher QAMs */ + if (p->u.qam.modulation == QAM_128 || + p->u.qam.modulation == QAM_256) + stv0297_writereg_mask(state, 0x88, 0x08, 0x00); + else + stv0297_writereg_mask(state, 0x88, 0x08, 0x08); + stv0297_writereg_mask(state, 0x5a, 0x20, 0x00); stv0297_writereg_mask(state, 0x6a, 0x01, 0x01); stv0297_writereg_mask(state, 0x43, 0x40, 0x40);
