Tested with rc5 - same results. It was suggested that I run slabtop when the system freezed, so here is that info: (again, by hand, I'm getting another machine to use either netconsole or a serial cable).
Active / Total Objects (% used) : 478764 / 485383 (98.6%) Active / Total Slabs (% used) : 14618 / 14635 (99.9%) Active / Total Caches (% used) : 79 / 138 (57.2%) Active / Total Size (% used) : 56663.79K / 57566.41K (98.4%) Minimum / Average / Maximum Object : 0.01K / 0.12K / 128.00K
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 403088 403088 100% 0.06K 6832 59 27328K nfs_page 30380 30380 100% 0.50K 4340 7 17360K nfs_write_data 15134 15134 100% 0.27K 1081 14 4324K radix_tree_node ...
The other thing is that the stack trace showsd slabtop as being halted in throttle_vm_writeout while allocating memory, and the writetest was halted waiting to allocate memory.
I'll get more detailed stack traces once I get the second machine set up.
