Hi, I've compiled kernel 2.5.8 under RedHat 7.2 using gcc 3.04; it was impossible to compile Intel i810 VGA drivers, and SCSI AHA154x, AHA17... too: the relative code tries to access to an inexistent member 'address' of struct nbd_device (pheraps they means dma_address?). Anyway, it works. Now, the runtime problems: 1) Sound - I compiled both OSS and ALSA as module, but RedHat sndconfig does not recognize any of them (sndcore not found): must I include OSS support directly in the kernel? 2) External standard serial modem - All hardware is recognized, but my serial modem in /dev/ttyS1 is not found ?!? At a first look, seems that DOS COM2, /dev/ttyS1 in 2.4.x kernel, became /dev/ttyS01 in 2.5.8 kernel. Is it possible? Emilio -- Kernelnewbies: Help each other learn about the Linux kernel.
