Could someone let me know how to use Magic Sysrq? (should it be Alt-Sysrq + p or Alt -SysRq + t or Alt-Sysrq + m). Also I noticed that sysrq is currently disabled on the Fedora Core 5. Is there anyway I can enable sysrq (I am not sure if writing to /proc/sys/kernel/sysrq would do the trick) And also how can I analyse the crash dump produced by Magic Sysrq? Thanks, Avinash.

But anyway, when did it happen? on the 1st iteration (that iterates over overwrite_num)? OK, maybe Magic SysRq can find out where it stucks.... Hang usually means "locked" or "race" somewhere. regards, Mulyadi
