Hi All, I've been noticing some differences using PCI devices in 2.6 kernels between a Blade 100 and Blade 1000.
On a Blade 100, I've gotten a PCI USB2 controller (NEC chipset) to work using the ehci driver with no problems as well as a PCI cs46xx sound card (Hercules GameTheater XP). However, when I try to use the same cards in the Blade 1000, the drivers appear to have issues getting IRQs when the drivers load. Below is sample output from the 2.6.13 kernel of what happens when the drivers attempt to load; USB controller; ehci_hcd 0001:00:01.2: NEC Corporation USB 2.0 ehci_hcd 0001:00:01.2: reset hcs_params 0x2385 dbg=0 cc=2 pcc=3 !ppc ports=5 ehci_hcd 0001:00:01.2: reset portroute 1 0 1 0 0 ehci_hcd 0001:00:01.2: reset hcc_params 0002 thresh 0 uframes 256/512/1024 ehci_hcd 0001:00:01.2: new USB bus registered, assigned bus number 1 ehci_hcd 0001:00:01.2: request interrupt 10,20e failed ehci_hcd 0001:00:01.2: USB bus 1 deregistered ehci_hcd 0001:00:01.2: init 0001:00:01.2 fail, -16 ehci_hcd: probe of 0001:00:01.2 failed with error -16 ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) ohci_hcd: block sizes: ed 80 td 96 ohci_hcd 0001:00:01.0: NEC Corporation USB ohci_hcd 0001:00:01.0: new USB bus registered, assigned bus number 1 ohci_hcd 0001:00:01.0: request interrupt 10,20c failed ohci_hcd 0001:00:01.0: USB bus 1 deregistered ohci_hcd 0001:00:01.0: init 0001:00:01.0 fail, -16 ohci_hcd: probe of 0001:00:01.0 failed with error -16 ohci_hcd 0001:00:01.1: NEC Corporation USB (#2) ohci_hcd 0001:00:01.1: new USB bus registered, assigned bus number 1 ohci_hcd 0001:00:01.1: request interrupt 10,20d failed ohci_hcd 0001:00:01.1: USB bus 1 deregistered ohci_hcd 0001:00:01.1: init 0001:00:01.1 fail, -16 ohci_hcd: probe of 0001:00:01.1 failed with error -16 Sound controller; unable to grab IRQ 8752768 Sound Fusion CS46xx: probe of 0001:00:02.0 failed with error -16 At first I was thinking that maybe there was an issue with the PCI bus on the Blade 1000, but I have a r8169 chipset based Gigabit Ethernet card in there and that works just fine. The IRQ it shows its using when the driver loads seems a bit high, but doesn't seem to affect performance. Kernel output from the driver loading for that is; r8169 Gigabit Ethernet driver 2.2LK-NAPI loaded eth0: Identified chip type is 'RTL8169s/8110s'. eth0: RTL8169 at 0x7fe00134000, 00:c0:49:fa:1d:71, IRQ 8752896 I've also tried rotating the location of the PCI cards around a bit based on the 33MHz and 66MHz PCI slots, but no noticeable difference in behaviors. For reference, I've included the lspci output from the Sun Blade 100 and Sun Blade 1000. Sun Blade 100; 0000:00:00.0 Host bridge: Sun Microsystems Computer Corp.
