So, we still have to wait for the exact explanation... Thanks very much Marcin! I think, there is this one possible for your testing yet?: Subject: [patch] genirq: temporary fix for level-triggered IRQ resend Date: Wed, 8 Aug 2007 13:00:37 +0200 If it's not a great problem it would be interesting to try this with different CONFIG_HZ too e.g. you could start with 100 (I guess, you tested very similar thing in 2.6.23-rc2 with 1000(?) already). Jean-Baptiste: you can skip/break testing of this 'experimental' patch, too.
