Reply-To: James.Bottomley@SteelEye.com Could you keep the cc: list when replying, otherwise we lose the tracking information in the bug database and on the list. Could you try this again with 2.6.15, and then I can try giving you some sysfs settings to prod to see if the driver can be forced up to 50ns.

I have the same problem since kernel 2.6.13 on a "Fedora" system but verified it by means of a "Ubuntu" live CD. Only "FAST-10" mode is negociated for a Quantum Atlas 10k3 disk connected to the on-board AIC-7880 UW-SCSI chip of my PR440FX mainboard. For 2.6.12 kernels and earlier, the nominal transfer mode was 40 MB/s. See the attached "dmesg" output for the "Ubuntu" (2.6.15-15-386) kernel. I had posted the original bug back in October 2005 at: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=171282 PS: Please do not reply to a post and include the old message(s). This bug record is already really too big, thanks!
Created attachment 7475 [details] "Ubuntu" log file dmesg-(2.6.15-15-386) for AIC-7880 and Quantum Atlas 10k3
I tried: $ echo 50 > /sys/class/spi_transport/target0:0:0/period $ fdisk /dev/sda $ cat /sys/class/spi_transport/target0:0:0/period on my PR440FX box. No improvement. The value of "period" still equals 100. This issue is due to a regression of 2.6.13 and later. Why would one need to "force" 50ns, when the controller is an U-SCSI one for which 20 MHz (50ns) should be the default value?
This extremely annoying bug is still present in 2.6.17rc2-git3.
Still only half speed for 2.6.17rc3-git12.
Still present in 2.6.17rc6.
Kernel version 2.6.18rc4 still negotiates "FAST-10" whereas it should be "FAST-20" for my on-board "AIC-7880" controller connected to a "QUANTUM Atlas 10k3" disk. The system board is an "INTEL PR440FX".
Is this issue still present in kernel 2.6.19?
Yes, it is, at least for "kernel-2.6.19-1.2788.fc7.i686". Just before the kernel panic which occurs because of "initrd" issues with current "Fedora Development", the already known message "FAST-10 ..." is issued.
Still only half speed for 2.6.21.2.
Any updates on this bug? Thanks.
(In reply to comment #17) > Any updates on this bug? No, still only half speed for kernel version 2.6.23-rc0-git16.
Joachim, please have a look at http://bugzilla.kernel.org/show_bug.cgi?id=8366, see if this is the same (or a related) problem?
In case of bug #8366, it's problem of wrong detection of wide/narrow devices, right? In my case, it's a matter of synchronous vs. asynchronous mode which leads to an effective 50% loss in transfer rate. However, following some hints borrowed from the other bug report, I tried the following: echo 50 > /sys/class/spi_transport/target0:0:0/min_period echo 50 > /sys/class/spi_transport/target0:0:0/period echo 1 > /sys/class/spi_transport/target0:0:0/revalidate After issuing these commands, additional lines appear in /var/log/dmesg, namely: target0:0:0: Beginning Domain Validation target0:0:0: asynchronous target0:0:0: wide asynchronous target0:0:0: FAST-20 WIDE SCSI 40.0 MB/s ST (50 ns, offset 8) target0:0:0: Domain Validation skipping write tests target0:0:0: Ending Domain Validation whereas -before- it would have read: target0:0:0: Beginning Domain Validation target0:0:0: asynchronous target0:0:0: wide asynchronous target0:0:0: FAST-10 WIDE SCSI 20.0 MB/s ST (100 ns, offset 8) target0:0:0: Domain Validation skipping write tests target0:0:0: Ending Domain Validation This is interesting, since instead of FAST-10 mode, now FAST-20 mode appears to have been negociated. The strange thing is that even in single user mode, this increases the transfer rate as measured by 'hdparm' from a mere 18 MB/s to about 20 MB/s whereas up to kernel version 2.6.12, I easily achieved 28 MB/s even in multiuser mode. However, there is this suspicious 'asynchronous' attribute reported by 'dmesg'. Is there a way to force snychronous mode?

The crucial quantity in my case actually is: /sys/class/spi_transport/target0:0:0/min_period because unless I set this quantity to 50, it's simply impossible to reduce the value in '../target0:0:0/period'. Btw, after writing 1 to '../target0:0:0/revalidate', the value in '../target0:0:0/period' is actually updated, so this seems to be equivalent to 'fdisk /dev/sda'. I hadn't mentioned it explicity, but I am of course able now to set '../target0:0:0/period' to both 50 and 100 which is verified by dumping its content and checking the corresponding entries in '/var/log/dmesg'.
(In reply to comment #21) The correct procedure is definitely to issue the two following commands: echo 50 > /sys/class/spi_transport/target0:0:0/min_period echo 1 > /sys/class/spi_transport/target0:0:0/revalidate The content of 'period' is then automatically updated accordingly as I have verified by writing 50 and 100 alternately to 'min_period' followed by a revalidation. It is -not- necessary to write a new value to 'period' after modifying the content of 'min_period'. The suggestion to modify 'period' only and to issue 'fdisk /dev/sda' thereafter does -not- work because the current value of 'min_period' blocks application of any smaller value to 'period'. In the meantime, I have verified that switching to 'FAST-20' actually -does- the right thing. By using a 'Ubuntu' live CD where the hard disk is not at all used by the system itself, I obtain a satisfactory transfer rate of 32 MB/s for my U160 hard disk connected to an onboard AIC7880 controller. The lower values reported in comment #20 where due to using a 'Fedora' -development- kernel [2.6.23-0.49.rc1.git3.fc8] which appears to have many nefarious debug options turned on. After booting the latest 'F7' update kernel [2.6.22.1-33.fc7], the transfer went up from 20 MB/s to about 28 MB/s which is reasonable. The remaining issue is thus to make the kernel negociate the correct mode. Once it is set, operation continues as expected.

The purpose of the test isn't to fix anything it's to get me more information about the problem. I theorise it's related to speed bounce negotiation that some devices do (get shocked by too low a period then bounce up to the safe 100ns). However, if your min_period for this device comes up as 100 then your particular problem is pilot error: you have the device set to 10MHz in the adaptec bios. If it comes up as < 50, then the nsvram routines aren't pulling the right value out. James

The relevant BIOS settings [I haven't found any other] of my onboard AIC-7880 controller currently are: - Initiate Sync Negotiation: yes - Maximum Sync Transfer Rate: 40.0 - Support for Ultra SCSI Speed: enabled Nothing questionable here, and yet, the initial value of 'min_period' is 100 when it should be 50. As a matter of fact, this is what this bug report is all about! Moreover, as I had pointed out in comment #7, the transfer rate got always negociated correctly up to kernel 2.6.12 [2.6.12.6 according to the original reporter], situation that ceased to exist for 2.6.13 and later versions. I can boot a sufficiently old Ubuntu live CD at any time, and it -does- provide the correct transfer rate without tweaking. I checked this many times in the past, the last time several weeks ago.

Amazingly enough, I managed to dig out an old 2940UW .. but it definitely works with the correct bios settings: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 <Adaptec 2940 Ultra SCSI adapter> aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs scsi 0:0:0:0: Direct-Access QUANTUM ATLAS IV 9 WLS 0B0B PQ: 0 ANSI: 3 scsi0:A:0:0: Tagged Queuing enabled.

Miroslav, Joachim, it is possible to try git bisecting this, starting from 2.6.12?
I have recently installed Fedora 9 w/updates on my PR440FX system, and up to kernel 2.6.25.x, I still do have to update the value of min_period [100 by default, now set to 50] in order to switch to the maximum allowd transfer of a nominal 40 MB/s. The system was out of service for a longer period of time, but I will follow the suggestion from comment 28 to pin down the culprit.
