Con,


I did not mention before, I thought it was a fluke on my system. Now its affecting two systems since applying ck7.


<snip>
hda: dma_intr: status=0x58 { DriveReady SeekComplete DataRequest }

ide: failed opcode was: unknown
hda: set_drive_speed_status: status=0x58 { DriveReady SeekComplete DataRequest }ide: failed opcode was 100
hda: dma_intr: status=0x58 { DriveReady SeekComplete DataRequest }

ide: failed opcode was: unknown
hda: set_drive_speed_status: status=0x58 { DriveReady SeekComplete DataRequest }ide: failed opcode was 100
hda: CHECK for good STATUS
<snip>

That is happening while applying the dma settings to the hard drive.

In both cases, the drive is a Western Digital 40GB hard drive. That is the only solid commoniality. One is a P4 2.8, the other a P4 2.4. Intel Chipset + Intel IDE in one, Intel Chipset + HighPoint chipset in the other.

However, the code is exactly the same.


Thanks,
Joshua

First off - this has been a landmark improvement for me. Running an "emerge -a world" on my system has gone from a matter of minutes to a matter of seconds.

The performance has been !outstanding!. [Disclosure: Using NVIDIA Binary Drivers]


Great to hear. Thanks for feedback.

Not sure about the xfs one... perhaps it's related to the cfq one.

Badness in cfq_sort_rr_list at drivers/block/cfq-iosched.c:428


Known issue. There is a fix posted already in my ckdev directory (as posted by Jens Axboe). The stack dump, while annoying and causes a stall for a couple of seconds I believe, is harmless. Please apply the cfq2 fix in my ckdev directory for this to go away.
