I've got a problem. When I suspend my laptop (Lenovo X100e, dmesg
below), it suspends just fine, and resumes well too (thanks for that!).
But after resume I see high interrupt rates (like 77%) in top and
vmstat, it feels slower and fan never stops. Any ideas?
% top:
CPU0 states: 0.8% user, 0.0% nice, 0.6% system, 83.6% interrupt, 15.0% idle
CPU1 states: 3.6% user, 0.0% nice, 3.4% system, 0.0% interrupt, 93.0% idle
% vmstat -iv
interrupt total rate
irq0/clock 185246 199
irq0/ipi 225445 242
irq0/ipi_nop 216556 232
irq0/ipi_flushfp 32 0

irq145/pckbc0 3023 3
irq146/pckbc0 3826 4
Total 687383 739
(I hacked ipi.c a bit to get this output, patch below).
