Netdevice 0 : SLIRP backend - command line: 'slirp' mconsole (version 2) initialized on /home/bill/.uml/wksNEk/mconsole Partition check: ubda: unknown partition table Initializing stdio console driver NET4: Linux TCP/IP 1.0 for NET4.0 IP: routing cache hash table of 512 buckets, 4Kbytes TCP: Hash tables configured (established 2048 bind 4096) Linux IP multicast router 0.06 plus PIM-SM NET4: Unix domain sockets 1.0/SMP for Linux NET4.0. Kernel panic: Segfault with no mm Without the eth0=slirp parameter, there are no kernel panic. So at least the error message has changed. The host kernel has the skas patch from the Debian package applied. Cheers, -- Bill.
