Hmm.. I would have thought that the card was only DMA:ing video to the
framebuffer via PCI write commands. Could it be the Cypress that is
doing the bad access?
I've since my last mail had a problem with my SCSI DVD reader too. I've
got several oopses while reading data from a cdrom, still using 2.3.47:

I've also tried 2.3.99-pre5, and it did compile and boot but I can't get
my bttv to work. There seems to be some problem with shared memory:

I've recompiled the binary using the new linux headers, but that didn't
help. I saw this message while running 2.3.99-pre5:
shmget: shm filesystem not mounted
What does this mean?
--NFS doesn't work either:
root@ymer ~ #modprobe nfs /lib/modules/2.3.99-pre5/fs/nfs.o: unresolved symbol xdr_two sunrpc: Device or resource busy
depmod does not complain on the nfs.o, though.

Another thing, I get a lot of these messages while accessing a NetBSD-current NFS server:
nfs_writepage_sync: prior time?? nfs_writepage_sync: prior time?? nfs_writepage_sync: prior time?? nfs_writepage_sync: prior time??
What's wrong?
