Binary package hint: firefox
Sometimes when resuming from suspend-to-RAM, Firefox becomes unresponsive while using 100% CPU time. An strace shows it in a cycle like this:
--- SIGIO (I/O possible) @ 0 (0) ---
rt_sigreturn(
futex(0xb2503d90, 0x80 /* FUTEX_??? */, 2) = ? ERESTARTSYS (To be restarted)
This repeats endlessly and uses all available CPU time. It doesn't always happen, and I haven't noticed a pattern yet, but it's happened 3 or 4 times in the last week.
