There seems to be a problem with nested locks. What was the panic message? Try deleting the code in the SMP ifdefs in cy.c, and don't use fast interrupts with SMP: (a) for the pci version, don't use option CY_PCI_FASTINTR. (b) for the isa version, delete the line with RI_FAST in it in cy.c. Bruce To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
