On a fresh boot with the latest kernel and userland, it gets as far as: remote: Enumerating objects: 1314, done. [...] Updating 6f8a947161..562a8eaddf This is where it freezes and the disk churning stops. The console partially freezes up too. I'm able to switch ttys with alt+f2/3= but can't actually type a username at the login prompt. After some time, the console then (repeatedly, but slowly) prints: swap_pager: indefinite wait buffer: bufobj: 0, blkno xxx, size: 4096 (The xxx is a random number every time, with some repetitions.) I have to hard reset it. I tried with swap off but that didn't help. Of not= e is that wired memory in top at the time of the hang goes way up to 9gb (out of 10gb total) but the ARC is only around 250mb total. This is all done on a f= resh boot. Kernel stable/13-889517034 (from September) doesn't have the bug. --=20 You are receiving this mail because: You are the assignee for the bug.=
