During this time, the VM process is eating all the CPU time during the decompression, like an infinite loop. Between these 2 strings is the gunzip() function at boot/compressed/misc.c which does the real job, and the problem seemed to appear since commit 1ab60e0f72f71ec54831e525a3e1154f1c092408. (2.6.22-rc1 hangs, 2.6.21.6 works). The problem occurs with or without CONFIG_RELOCATABLE enabled. What are the possible solutions to confirm where the problem is coming from ? Thanks, Gabriel
