Hi forum,
my beloved long running Home Theater PC developed an annoying behaviour of filling the log files
+ messages
+ syslog
+ kern.log
quickly to a degree that prevents from starting X afterwards.
The log entry that repeats is this:
Code:
Oct 13 18:12:13 hostname kernel: [ 494.255061] bt878(0): irq PPERR risc_pc=7b769208
Oct 13 18:12:13 hostname kernel: [ 494.255073] bt878(0): irq PPERR risc_pc=7b769008
Oct 13 18:12:13 hostname kernel: [ 494.255092] bt878(0): irq PPERR risc_pc=7b769010
Oct 13 18:12:13 hostname kernel: [ 494.255109] bt878(0): irq PPERR risc_pc=7b769010
Oct 13 18:12:13 hostname kernel: [ 494.255127] bt878(0): irq PPERR risc_pc=7b769010
Oct 13 18:12:13 hostname kernel: [ 494.255147] bt878(0): irq PPERR risc_pc=7b769010
Oct 13 18:12:13 hostname kernel: [ 494.255164] bt878(0): irq PPERR risc_pc=7b769010
Oct 13 18:12:13 hostname kernel: [ 494.255186] bt878(0): irq PPERR risc_pc=7b769010
The number at the end of the line rises from 008 to 200 and then starts over at 008.
The
bt878 part is a strong hint that my Pinnacle PCTV Sat is the problem here. Furthermore the problem only arises while using the PCTV Sat, be it in MythTV or VLC.
Possibly connected is an error that keeps popping up on every console (regardless of using the PCTV Sat or not)
Code:
kernel:do_IRQ: 1.92 No irq handler for vector (irq -1)
Which makes using the console nearly impossible. That's why this message is suppressed by kernel parameters
Continually truncating the log files is not an option because the amount of writing will kill the harddisk pretty quickly.
How can I track down the log-filling error?
Here is some information about my PC:
