Comment 64 for bug 479296

I have the same problem - freezing Ubuntu 9.10.
I have the same thing in the log:
Mar 16 11:04:33 ubuntu pulseaudio[2293]: ratelimit.c: 157 events suppressed
Mar 16 11:06:46 ubuntu pulseaudio[2293]: ratelimit.c: 159 events suppressed
Mar 16 11:06:54 ubuntu pulseaudio[2293]: ratelimit.c: 158 events suppressed

I have disabled the ACPI in BIOS and no reboot for an hour. I will tell you later if it helped me or not.

No in the logs I have:
