Maybe the following is helpful or of interest for haiku-developers:
I installed Haiku-r23625 on a HDD-partition of my Thinkpad (1536 MB RAM, Pentium M, 1,7 GHz, 120 GB HDD, ATI Radeon 7500, AC97-sound).
Booting is OK. Graphics is well, but no sound. After some minutes of usage comes KDL with message "USB ControllPipe: timeout waiting for queued request to complete" and "PANIC:free(): address 0x90b53c50 already exists in bin free list". It seems to depend on anyone USB-device (mouse).
