I got the above panic on my NetBSD/Atari 1.4Z while playing an mp3 file
with amp. This was my first try on mp3, so no, it has never worked before.
The sound card plays .au files without problems. Does anyone have ideas
where I should start searching for the bug?

Soundcard detect:
  pci0 at pcibus0
  eso0 at pci0 dev 0 function 0: ESS Solo-1 PCI AudioDrive ES1946
  eso0: interrupting at irq 3
  eso0: mapping Audio 1 DMA using VC I/O space at 0xb0004300
  audio0 at eso0: full duplex, mmap, independent

Panic trace:
  panic: pool_put: mclpl: page header missing
  Stopped in amp at    _cpu_Debugger+0x6:
