This laptop is an 'AMD Turion(tm) 64 X2 Mobile Technology TL-50' CPU, but its booting 32 bit SMP (make defconfig). No kernel built after this commit works for this platform. There is no crash output, it just wedges after 'NET: Registered protocol family 2'. How can I debug this problem? rtg -- Tim Gardner tim.gardner@ubuntu.com
