![]() I recently discovered a bug on PPC which causes the floating point registers to get corrupted when CONFIG_PREEMPT=y. The problem occurred while running a multi threaded Java application that does floating point. The problem could be reproduced in anywhere from 2 to 6 hours. With the patch I have included below it ran for over a week without failure.
