race in expand_stack in 2.6.7 ?
G'Day.
Some months ago i've reported about bug which Andrea defined as "race in expand_stack with threads" (http://lkml.org/lkml/2004/4/14/52),
but it was related to -aa branch (More precisely 2.6.5-aa5). After applied patch from Andrea (many tnx), i did not notice any troubles with 2.6.5-aa5 and later with 2.6.7 until today when i've caught very similar bug(?) on the same system. [Dual P4 Xeon 2.4GHz, 2G ECC RAM - (production web-server) Gentoo, kernel 2.6.7]
System behaviour and trace are nearly the same, system alive but i couldn't do ps, pkill etc. Here is a trace:
