I'm not sure whether it's safe to assume that. Basically you're calling some sleepable functions like mutex or kmalloc with GFP_KERNEL inside the local irq-disabled context. This may not work.

Is that because using sleepable functions in irq-disabled context that it may causes the irq disable too long then causes hard lock?

Not only too long. Since the code path already disabled non-boot CPUs, it means the system may get stuck completely. In anyway, I merged the patch to SLE and openSUSE branches. Let's close this bug for now. Feel free to reopen if you still see the problem. Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
