Gentoo on sheevaplug: Unknown HZ value! problem
I was following the instruction from http://www.gentoo.org/doc/en/handbook/handbook-arm.xml?part=1&chap=7 trying to put Gentoo onto my sheevaplug. Everything seems to be functioning except I couldn’t get the login prompt to appear through the usb-serial port, but I was able to ssh to the box though. The complete booting message reads

[ System is ready at this point, but the login prompt just can't show up; I am able to ssh to the box though. ]
I haven’t found any solution (tried re-installing procps as suggested by some posts but it didn’t help) yet to this problem. I also tried the vinilla-sources-22.214.171.124 kernel, but the problem remains the same. Maybe it’s time to file a bug report with Gentoo.
Edit [ July 6th, 2009 ]:
Today I solved half of the problem, the reason why I couldn’t get a login prompt through the serial port is line #39 in /etc/inittab
After change that line to
I finally had the login prompt appear as it should.
