11 Ah, that bug. Been a while indeed. My R10K IP28 is in the closet and R10K
12 O2, last time I tried a kernel, hated me rather fantastically.

14 The Octane, on the other hand, partially boots now in 3.14.1. At least, I
15 can get to a working Odyssey console w/ SCSI, keyboard, and even the mouse
16 looks to work. Still fighting the IOC3 over RTC interrupts, and SCSI is
17 abysmally slow (too many interrupts, I think -- ~4MB/sec r/w). But it works
18 again. No serial, RAD1, Impact or SMP yet.

20 When I fix a few more things, I'll probably attempt to bootstrap a new
21 userland on it. Current one is from 2009. So, when that happens, I'll be
22 able to re-verify glibc and the R10k thing again, I guess.
