Yes (test with the same binary): bash-2.05b# while /bin/true; do /bin/true; done Kernel panic: Kernel mode fault at addr 0x1f, ip 0x400d1397 However, I discovered that an old 2.6.0 kernel works well. I think that had= =20 2.6.0-test9 patch; so I think that this is related with the NET: Registered= =20 ... hang, which was solved with the same patch. That does not happen on=20 different compilation env.s, but I think that is random: a crazy pointer=20 failing in different places. --=20 Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
