That at least has the potential to get you six working devices, and half a dozen other working devices, for a total of 12. With no unnecessary resets or long timeouts!

RE: [2/3] 2.6.22-rc3: known regressions v2
Agree, but overstated somewhat. The card in question that the regression is reported against is not a released card and as such could have a flawed environment, Hardware, Firmware or other Incompatibility. The fix for the root cause will likely not touch the driver or the kernel. It does raise the specter of a possible follow-on patch to address the root cause under kdump should we determine that the problem can not be solved in time of release of the Firmware of the current pre-released card or if we discover that other released cards have a similar Firmware or Hardware bug. Speculation such as these do not belong on kernel regression reports IMHO.

No guarantee it will make 2.6.23 either, since it is low priority :( Could you summarize what other regressions were reported? I can't find much information about sata_mv regressiobs on linux-ide list (at least when looking at the subjects: lots of patches from you, and two reports from me). Dave Dillow and dean gaudet responded with reports that the BUG_ON/WARN_ON traps in would trigger: WARNING: at drivers/ata/sata_mv.c:1287 mv_qc_issue() and WARNING: at drivers/ata/sata_mv.c:1333 mv_get_crpb_status() which leads me to think that my sata_mv new-EH patches are accidentally turning on NCQ mode.

Re: HPT374 IDE problem with 2.6.21.* kernels

After upgrading from 2.6.20.7 kernel to 2.6.21.1 my system started to reset infrequenly the IDE bus. In the syslog DMA timeout, resetting IDE bus messages appeared. I've changed the two disks attached to the HPT374 controller, and always the first disk had problems. I've replaced cables, plugged the disks into other IDE ports, but it was only a matter of time to experience an IDE reset. When I upgraded to 2.6.21.3 the resets became much more frequent, this time even DMA was disabled too on the first disk. I turned DMA back Manually with hdparm, and a few seconds of intense IO activity resulted in another IDE reset. Reverting back to 2.6.20.12 the problem seems to be gone. BTW I'm using the PATA driver for the HTP374, not the libata one. Is this a known problem/ is there a way I can help locating the cause of the problem? Yes, please post the boot log and the IDE reset log too for starters... (cc's added) WBR, Sergei Hi, The log of a typical IDE reset is available here: http://petra.hos.u-szeged.hu/~wildy/syslog.gz This was the worst case: the IDE bus was resetted during the system boot.

Could you try setting HPT374_ALLOW_ATA133_6 to 0 in drivers/ide/pci/hpt366.c and rebuild/reboot the kernel? Hi Sergei, This looks promising. Using a vanilla 2.6.22-rc3 I was able to reproduce the problem within a few seconds. With the above modification the machine is running under heavy disk I/O without problems since 30 minutes...

I'm not sure which of the two methods was selected by libata (probably the memory interface). I am very CF-ignorant. How does libata select a memory or I/O interface on a CF device? Right. Usually we cannot select them, as it's the wires between the ATA chipset (motherboard) and the CFCARD that determine this. CF cards support 3 modes (MEM, I/O and True IDE), and neither MEM nor I/O modes can talk IDE. Most often, the PIN 9 is simply shorted to the ground at the connector to set the card in True IDE mode, which makes it emulate a standard IDE disk.
