I just updated src on blade 1500, made buildworld, buildkernel, installkernel, no problem there. On reboot in single user mode I get this panic: uart0: console (9600,n,8,1) uart1: <16550 or compatible> at port 0x2e8-0x2ef irq 44 on isa0 uart1: [FILTER] Timecounter "tick" frequency 1503000000 Hz quality 1000 Timecounters tick every 1.000 msec IP Filter: v4.1.28 initialized.
