I noticed it doesn't soft reset anymore once the kernel said: ata1.00: limiting speed to MWDMA1:PIO4 # lspci 00:00.0 Host bridge: Intel Corporation E7320 Memory Controller Hub (rev 0c) 00:00.1 Class ff00: Intel Corporation E7320 Error Reporting Registers (rev 0c) 00:02.0 PCI bridge: Intel Corporation E7525/E7520/E7320 PCI Express Port A (rev 0c) 00:03.0 PCI bridge: Intel Corporation E7525/E7520/E7320 PCI Express Port A1 (rev 0c) 00:1c.0 PCI bridge: Intel Corporation 6300ESB 64-bit PCI-X Bridge (rev 02) 00:1d.0 USB Controller: Intel Corporation 6300ESB USB Universal Host Controller (rev 02) 00:1d.1 USB Controller: Intel Corporation 6300ESB USB Universal Host Controller (rev 02) 00:1d.4 System peripheral: Intel Corporation 6300ESB Watchdog Timer (rev 02) 00:1d.5 PIC: Intel Corporation 6300ESB I/O Advanced Programmable Interrupt Controller (rev 02) 00:1d.7 USB Controller: Intel Corporation 6300ESB USB2 Enhanced Host Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 0a) 00:1f.0 ISA bridge: Intel Corporation 6300ESB LPC Interface Controller (rev 02) 00:1f.1 IDE interface: Intel Corporation 6300ESB PATA Storage Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 6300ESB SMBus Controller (rev 02) 01:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06) 01:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06) 03:02.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID (rev 01) 04:02.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 04:04.0 SCSI storage controller: Adaptec AHA-2940U/UW/D / AIC-7881U (rev 01) -- Tomasz Chmielewski http://wpkg.org
