Hi
I've started to use the latest 2.4.0-test10pre3 kernel - my IBM disk flyies at 33MB/s on my BP6 - however the amount of deadlocks is unbeliavable - when all my disks are at UDMA33 everything goes fine (0 deadlocks per day)
However when I use hpt UDMA66 controler and the latest kernel its quite easy to lock my machine - like doing several IDE operations in parallel - e.g. checksuming CDROM & copying some files from ext2 to vfat partition. (I'll have to prepare some test case for this and do it in console so maybe I could see some oops, but in my Xwindow session I couldn't see anything as even Sysrq doesn't work)
But its hard to tell if its problem with ATA or this is some fault of the VM system in 2.4 - is there anywhere backport of your IDE patch for 2.2.18pre17 ?? I think someone has anonnounced that he will maintain this backport instead of you?
(I have no deadlock when I use 2.2.17/8 kernels even with RTL - 300power supply and yes I get APIC errors - and also I've tried to run with noapic option with the same result)
