Hi there,
since upgrading my kernel to fedora 8 2.6.26.5-28.fc8 I'm getting error messages in dmesg:
[root at 192 ~]# dmesg | grep DVB
DVB: registering new adapter (TT-Budget/WinTV-NOVA-T PCI)
DVB: registering frontend 0 (LSI L64781 DVB-T)...
DVB: frontend 0 frequency limits undefined - fix the driver
DVB: frontend 0 frequency limits undefined - fix the driver

So, following the instructions I found on a Fedora mailing list by Andrew Junev;
http://www.redhat.com/archives/rhl-list/2008-September/msg02865.html
I added the drive to the blacklist:
[root at 192 ~]# cat /etc/modprobe.d/blacklist #
# Listing a module here prevents the hotplug scripts from loading it.
# Usually that'd be so that some other driver will bind it instead,
# no matter which driver happens to get probed first. Sometimes user
# mode tools can also control driver binding.
#
# Syntax: driver name alone (without any spaces) on a line. Other
# lines are ignored.
#
# Added to solve budget DVB errors in 2.6.26.x kernel
blacklist snd-aw2
# watchdog drivers
blacklist i8xx_tco
# framebuffer drivers
blacklist aty128fb
blacklist atyfb
blacklist radeonfb
blacklist i810fb
blacklist cirrusfb
blacklist intelfb
blacklist kyrofb
blacklist i2c-matroxfb
blacklist hgafb
blacklist nvidiafb
blacklist rivafb
blacklist savagefb
blacklist sstfb
blacklist neofb
blacklist tridentfb
blacklist tdfxfb
blacklist virgefb
blacklist vga16fb
# ISDN - see bugs 154799, 159068
blacklist hisax
blacklist hisax_fcpcipnp
----------------
Which doesn't make any difference. I'm still seeing the error messages in dmesg and the lspci -v is still seeing the module loaded. I think the modprobe.conf is aliasing the snd audio driver to my intel based onboard chipset, but I don't know if thats the right route to go down.
Thanks for any tips,
Giacomo
