The box is a sun4c architecture with integrated SunLANCE networking (external tranciver), cg3 framebuffer and 1 ESP SCSI controller. It is operated as a diskless workstation and works with 2.2 series kernels (2.2.26). As the idprom's battery is empty I boot it with the following commands: n # new command mode f idprom@ 1 xor f mkp # reset idprom 8 0 20 76 4c 78 c0ffee mkpl # set mac addr/host id boot net - ip=dhcp # boot linux Framebuffer =====While 2.2 works nicely with the framebuffer console, the first twist was a lockup at boot time, worked around by using the prom console. Sun LANCE ====Now I am stuck at IP auto configuration with "Sending DHCP requests ...... timed out!" While DHCP requests are being sent, neither does my switch show any activity, nor does tcpdump on the server report any packets being received. The card is detected properly though "sunlance.c:v2.02.... eth0: LANCE 08:00:20:76:4c.78" When I instead configure a fixed IP: boot net - ip.0.0.5:10.0.0.3:10.0.0.3:255.255.255.0::: nfsroot.0.0.3:/data/export/euler/root The machine get's stuck mounting the nfs-root: Looking up port or RPC 100003/2 on 10.0.0.3 portmap: server 10.0.0.3 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port or RPC 100005/1 on 10.0.0.3 NETDEV WATCHDOG: eth0: transmit timed out eth0 transmit timed out, status ff3c, reset Again, there is no activity, what so ever, on the wire (switch/tcpdump) DMA =All problems (see below) could of course be linked to this boot message? dma0 unknown dma version 70000000 ESP SCSI ==== Cannot find dvma for ESP0's SCSI ESP: Total of 1 ESP hosts found, 0 actually in use. This all happens either with a native, 2.95 compiled kernel, as with a 3.3.2 cross x86 compiled kernel. Any help would be appreciated. Thanks Uli
