Dear Tejun: My 5 cents: Just order the board. These stock PC hardware are too cheap these days, it doesn't make any sense to try to debug somewhat difficult problem remotely if the hardware is available on the market. Even if you have to spend your own money, it will be money well

Dear Tejun: The test results point to varied kinds and degrees of problems. At the moment. To avoid turning off anything fancy on systems involving SB600/700, we definitely need more info. Shane, can you please summarize chipset product lines and revisions and how they're configured

Hi Jeff: Do you have any suggestion on my plan to withdraw Tejun's forcing 32 bit DMA patch? As well as further validation to the 64 bit DMA capacity of SB600 SATA controller? Thanks Best Regards Shane -Original Message- From: Shane Huang Sent: Wednesday, January 23, 2008 3:44 PM

Hi Tejun: -Original Message- From: Tejun Heo [mailto:[EMAIL PROTECTED] But when I set OnChip SATA type into AHCI mode(SATA device ID 4391), the hotplug can work, and the device name will be changed from scd0 to scd1 during the hotplug. The log messages are attached at the end

Hi Tejun: That's strange. I guess we're forgetting something when forcing the controller into AHCI mode. Yes, it's strange. This issue also exists on RedHat RHEL5.1 and RHEL4.6 What happens if you manually issue re-scan by doing echo - - - /sys/class/scsi_host/hostN/scan where

Hi Tejun: Do you guys think it's normal? It not, how to make SATA hotplug work on different SATA port? Should it be supported by BIOS or hardware? If you connect it to a different port, the original device will die and new device will appear. That's the expected behavior. In the log, I

I would like those to be removed, but to be conservative we should first get some testing feedback that confirms this just like those provided to me from the AMD folks for the RS690, RX790 and RD580 cases. Otherwise the risk to break people's systems is very real. In fact, our team only

Hi David: I think this pretty much sums up the situation accurately. My suggestion is: 1) Leave the pci_intx() twiddling code in drivers/pci/msi.c 2) Add quirks for INTX_DISABLE turns off MSI too, this sets a flag in the pci_dev. 3) The pci_intx() calls in drivers/pci/msi.c are

From: [EMAIL PROTECTED] SB700 supports one physical IDE channel, but SB700 SATA controller supports combined mode. When the SATA combined mode is enabled, two SATA ports(port4 and port5) share one IDE channel from IDE controller, and PATA will share the other IDE channel. Our previous patch
