I've seen some traffic here to suggest that the problem was tracked down, but I saw nothing about it being solved completely. Currently my system hangs whenever an irq trap message appears, usually after some sort of disk io on SATA drives. Is it fixed in the GIT patchset recently posted or is this still open?


Are you referring to the "Losing ticks" bug? What is the exact error
message that you get? Does the system hang momentarily or have to be
rebooted?

No not the ticks bug.

ata3: irq trap
ata3: command 0x25 timeout, stat 0x50 host_stat 0x60
ata4: irq trap
ata4: command 0x25 timeout, stat 0x50 host_stat 0x20
ata4: irq trap
ata4: command 0x35 timeout, stat 0x50 host_stat 0x20
ata3: irq trap
ata3: command 0x35 timeout, stat 0x50 host_stat 0x60


Over and over in random orientations. System hangs on io momentarily, usually a few seconds. No fs errors, no other errors given. System also seems to have been kicked out of DMA mode at least for disks.




This has been fixed in the actual release of 2.6.16-ide1 which i've just booted into. DMA seems active (as you'd expect since non-dma isn't supported) and no irq trap delays. Everything is working good again, Now if there was a way to get the CF disk (doesn't do dma) working in pata, I'd be set.

ps. Thanks for the help, I wasn't aware of the ide1 patch to 2.6.16 before.
