Comment 69: It was Knoppix 6, a fine DVD included with the "Linux Format"
magazine, april 2009. It hung during shutdown too (not 100% sure).
Now, I'm trying the slightly older Ubuntu 8.10 32bit. Behaves exactly the same:
Linux ubuntu 2.6.27-7-generic #1 SMP Fri Oct 24 06:42:44 UTC 2008 i686
GNU/Linux
[ 3.000235] Clocksource tsc unstable (delta = -153532416 ns)
[ 4166.800360203] rt-benchmark: Not scheduled since 4081.927005633
Audio playback is smooth (as expected: audio susceptibility came later).
Comment 71: Elmar, thanks for the tips. But I have my doubts cmus could have
saved me with that hopelessly old Ubuntu 6.10, or that your mentioned Xorg bug
is sufficiently old to be applicable. However with OpenSUSE 11.3, my computer
sometimes suddenly ignored all user input (no kernel panic). The proprietary
Nvidia driver solved that for me.
I'm not really after testing audio anymore. What concerns me is that somewhere
between kernel 2.6.18 and 2.6.27, something created the very ability to hang
for unbounded time. At least on my computer. I hereby ask for help to verify
this. It would be very helpful if you could give rt-benchmark a try!
Also, there are people out there on similar bug reports, mostly having hangs
during boot. I honestly believe they should try:
sudo rt-benchmark t0.01 d0.01
and track down the unbounded hang. It would also be interesting to know whether
they have Phoenix BIOSes.
