I get this, across netconsole: [17179569.184000] console handover: boot [earlyvga_f_0] -> real [tty0] wanna take a look at why there's cruft in bootconsole->name please? in grub.conf I have kernel /boot/bzImage-2.6.21-rc7-mm1 ro root=LABEL=/ rhgb vga=0x263 netconsole=4444@192.168.2.10/eth0,5145@192.168.2.33/00:0D:56:C6:C6:CC profile=1 earlyprintk=vga resume=8:5 time and I'm using http://userweb.kernel.org/~akpm/config-sony.txt Thanks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
