Just to be sure: is it the driver with my patch or without the patch? The patch seems broken anyway, so abandon it, and check only without the patch from now on.
Have reverted to unpatched version, now logging kernel messages to a file. The attached is the output for debug=2 from running the mplayer with the oss proc fix. WARNING... the gzip expands to 4.5MB, which explains the overflow on the dmesg ring buffer. But only the first hundred lines and last ten are different, the rest are all the same as far as I could see.
The only things I noticed that does change is that the repeated lines start like this :-
Oct 23 20:45:28 sentry kernel: SBXFI: IRQ = 0x500 Oct 23 20:45:28 sentry kernel: SBXFI: POINTER = 0x3e0 Oct 23 20:45:28 sentry kernel: SBXFI: SET TIMER TICKS = 16 Oct 23 20:45:28 sentry kernel: SBXFI: POINTER = 0x3e0 Oct 23 20:45:28 sentry kernel: SBXFI: POINTER = 0x3e0
And that the pattern changes after a short time dropping one of the POINTER lines. Screen output below to show commands used.
