Soren,

This gentleman has an alpha which is panic'ing on boot after the recent round of ata changes. Its apparently following a null function pointer from atapi_attach().

Based on the hardware, he has either a CMD646 or Cypress chipset.

Is this enough to go on, or would you like more information?

Thanks,

Drew

Eek! So that's what that message means. Is there a 'quick primer on debugging kernels' somewhere to be found? I would find that _very_ interesting literature!

pc = 0x0 ra = 0xfffffc000038a7cc

Can you please find the ra?
