Hi All, I recently purchased a Cyclades Cyclom-Yo4p serial adapter upon booting i noted: Mar 5 09:15:47 gumbo /kernel: cy0: <Cyclades Cyclom-Y Serial Adapter> port 0xf4 80-0xf4ff mem 0xffbe8000-0xffbebfff,0xffbee800-0xffbee87f irq 17 at device 15.0 on pci0 Mar 5 09:15:47 gumbo /kernel: pci_map_int: can't allocate interrupt Mar 5 09:15:47 gumbo /kernel: cy0: driver is using old-style compatability shims Moving it to a different slot and removing the CY_PCI_FASTINTR resulted in the pci_map_int message going away. However, after the system starts to transfer data on a ppp link on the COM1 port, i get a panic in the interrupt arena. I did not include the DDB trace info, because i suspect there may be some bitrot in cy.c, and thought i would just fix it myself. It appears that the cy.c is based on sio.c. Is the current sio.c sufficiently newbus correct so that it could again be used as a model to "fix" cy.c? I am going to try the card in a remote kernel GDB setup soon, so if someone wants the trace et.al info... eric haug Saint Louis Univ Earth and Atmospheric Sciences To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
