Hi
at system shutdown when hwclock --systohc is called there's a
might_sleep error dump from the kernel in do_page_fault. I found that
the problem is when hwclock uses direct cmos access when there's no RTC
support in kernel and only when hwclock is compiled with -O3
hwclock does an atomic access achieved with __asm__ cli and sti. Is this
a hwclock bug? I suppose the kernel is not responsible for userland
disabling interrupts ... putting delays and printfs in hwclock either
makes the dump show a different backtrace (although still with 2
do_page_faults) or results in no dump at all.
2.6.0-test1 and test2
