Hi,
I have a PQI Turbo SATA DOM. It works well under Windows. I installed it in a SuperMicro motherboard, Intel 5000P chipset. The OS is Ubuntu 7.04, kernel 2.6.20-15. But the DOM is not appeared as a device node, and I found several error messages in kernel log.
[ 67.124299] ata2.00: qc timeout (cmd 0x91) [ 67.124306] ata2.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x4) [ 67.124309] ata2: failed to recover some devices, retrying in 5 secs [ 102.258334] ata2.00: qc timeout (cmd 0x91) [ 102.258341] ata2.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x4) [ 102.258344] ata2: failed to recover some devices, retrying in 5 secs [ 137.392654] ata2.00: qc timeout (cmd 0x91) [ 137.392661] ata2.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x4)
Actually I also have a PQI IDE DOM, it have same error with Ubuntu 7.04 / kernel 2.6.20-15. After I upgrade kernel to 2.6.22, the IDE DOM can work. But as for SATA DOM, I have no luck this time. Even with the newest kernel, 2.6.23.14 and 2.6.24-rc7-git6, the problem still exists. I also found an interesting matter. The Ubuntu 6.10, say kernel 2.6.15-28, can identify both IDE DOM and SATA DOM. But due to other critical problem, I can not go back to this old kernel.
Whats going on? The new kernel is even worse than old one. It seems the problem is existing in the ata_piix driver.
Best regards, Mao Rui
