Subject: anyone working on newbus version of Cyclades serial driver?
Sender: owner-freebsd-current@FreeBSD.ORG

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...
