I've been having a problem with ext4 metadata checksums, which use SSE
for large blocks, and traced it to kernel_fpu_end() disabling interrupts,
but had paused to debug this (I assumed well-tested) piece of kernel
code before pushing it harder.

In trying to track down a bug (see below), I noticed that
math_state_restore() in arch/x86/kernel/traps.c appears to unconditionally
disable interrupts when called. Is this intended behavior or a bug?
The bug in question is triggered by dumping core on an ecryptfs file
