I don't encounter NULL pointer dereference at get_stats() on native environment, but I encounter another problem on native environment; initialization of SATA device fails if "nolapic" is given. I don't have specific reasons to give "nolapic" option. This problem was found when I was trying to reproduce [Bug #12409] on native ThinkPad X60 environment. scsi0 : ahci scsi1 : ahci scsi2 : ahci scsi3 : ahci ata1: SATA max UDMA/133 abar m1024@0xee444400 port 0xee444500 irq 1275 ata2: DUMMY ata3: DUMMY ata4: DUMMY Marking TSC unstable due to TSC halts in idle usb 3-6: new high speed USB device using ehci_hcd and address 2 usb 3-6: configuration #1 chosen from 1 choice hub 3-6:1.0: USB hub found hub 3-6:1.0: 4 ports detected firewire_core: created device fw0: GUID 000ae40600522014, S400 ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata1.00: qc timeout (cmd 0xec) ata1.00: failed to IDENTIFY (I/O error, err_mask=0x4) ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Full log for 2.6.28.5 without "nolapic" option: http://I-love.SAKURA.ne.jp/tmp/dmesg-2.6.28.5-native.txt Full log for 2.6.28.5 with "nolapic" option: http://I-love.SAKURA.ne.jp/tmp/dmesg-2.6.28.5-native-nolapic.txt Full log for 2.6.27.16 without "nolapic" option: http://I-love.SAKURA.ne.jp/tmp/dmesg-2.6.27.16-native.txt Full log for 2.6.27.16 with "nolapic" option: http://I-love.SAKURA.ne.jp/tmp/dmesg-2.6.27.16-native-nolapic.txt Full log for 2.6.26.8 without "nolapic" option: http://I-love.SAKURA.ne.jp/tmp/dmesg-2.6.26.8-native.txt Full log for 2.6.26.8 with "nolapic" option: http://I-love.SAKURA.ne.jp/tmp/dmesg-2.6.26.8-native-nolapic.txt Config: http://I-love.SAKURA.ne.jp/tmp/config-2.6.27.16 http://I-love.SAKURA.ne.jp/tmp/config-2.6.28.5 2.6.27.16 and 2.6.28.5 fail with this problem. 2.6.26.8 does not fail with this problem.
