Hi all, I compiled and tested the latest kernel (from git) for mips on an SGI O2, in order to check if it fixes a few problems my current kernel has. The first problem is that a PCI board with a PCI-to-PCI bridge is not correctly managed. The second problem is the CONFIG_BUILD_ELF64 options that made all new kernels since 2.6.20 unbootable. Of course unsetting CONFIG_BUILD_ELF64 worked, and the new kernel booted correctly. About the first problem, once the machine booted, the lspci command stil does not list the available devices on the board. The only listed device is the PCI bridge. The relevant parts in syslog are these lines [...] Sep 29 00:42:49 sgi kernel: SCSI subsystem initialized Sep 29 00:42:49 sgi kernel: PCI: Bridge: 0000:00:03.0 Sep 29 00:42:49 sgi kernel: IO window: disabled. Sep 29 00:42:49 sgi kernel: MEM window: disabled. Sep 29 00:42:49 sgi kernel: PREFETCH window: disabled. Sep 29 00:42:49 sgi kernel: PCI: Setting latency timer of device 0000:00:03.0 to 64 Sep 29 00:42:49 sgi kernel: Time: MIPS clocksource has been installed. Sep 29 00:42:49 sgi kernel: NET: Registered protocol family 2 [...] Is this a normal behaviour? Should/can I "enable" these windows in any way? I also noticed two new problems in this kernel: A. the connection via an e100 network board is *really* slow: an ssh connection with public keys take about 40 seconds before the prompt appear. B. recompiling with 8mb of frame buffer give an unusable display and fill my syslog of these messages: [...] Sep 27 08:59:18 sgi kernel: CRIME memory error at 0x1800ace0 ST 0x02010000<INV,GBE,NONFATAL> Sep 27 08:59:18 sgi kernel: CRIME memory error at 0x1800c8e0 ST 0x02010000<INV,GBE,NONFATAL> Sep 27 08:59:18 sgi kernel: CRIME memory error at 0x1800e4e0 ST 0x02010000<INV,GBE,NONFATAL> [...] Thanks a lot, Giuseppe
