I just upgraded my UP1000 from 4.7-stable to 5.0. Only weird thing left is the console seems to drop a lot of characters just after syscons takes over. I see this on console: <...> ppc0: interrupting at ISA irq 7 sc0: <System console> on isa0 sc0: VGA <16 virtual consoles, flags=0x0> net.inet.udp.blackhole: 0 -> 1 Doing initial network setup: host.conf hostname domain. <...> And this (correct output) in dmesg: ppc0: interrupting at ISA irq 7 sc0: <System console> on isa0 sc0: VGA <16 virtual consoles, flags=0x0> sio0 at port 0x3f8-0x3ff irq 4 on isa0 sio0: type 16550A, console sio0: interrupting at ISA irq 4 sio1 at port 0x2f8-0x2ff irq 3 on isa0 sio1: type 16550A sio1: interrupting at ISA irq 3 vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0 Timecounters tick every 0.976 msec Timecounter "i8254" frequency 1193182 Hz Timecounter "alpha" frequency 598976859 Hz ad2: DMA limited to UDMA33, non-ATA66 cable or device ad2: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata1-master UDMA33 acd0: CDROM <CD-ROM CDU4011> at ata1-slave PIO4 Mounting root from ufs:/dev/ad2a Note that everything past sc0 seems to have disappeared until it re-appears partway through multi-user startup. Its not a sysctl on a comcontrol thing, because booting single-user is similar. The output stops after sc0, and starts again when I hit return. This is a serial console, connected to a 5.0 x86 running conserver 8.5 on an 8-port comtrol rocketport card. The speed is only 9600 baud, and the console server seems to be able to handle it, so I think the problem is at the alpha end..
