Subject: 2.6.24-rc3: High CPU load -- hardware interrupts
Date: Sun, 18 Nov 2007 21:53:06 +0000 (UTC) [thread overview]
Message-ID: <slrnfk1d21.229.joerg@alea.gnuu.de> (raw)
Hi,
I've installed the new kernel version and now suspend to RAM works. But I
saw that the CPU load is everytime 50% due to hardware interrupts. Is
this a known bug?
