I've found a couple of bugs so far... 1. I did `modprobe kvm' and then tried running a version of the KVM Qemu compiled for a different kernel. My mistake. But I got an oops: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000008 printing eip: f91f9c3f *pde = 00000000 Oops: 0000 [#1] SMP last sysfs file: /devices/system/cpu/cpu0/cpufreq/scaling_max_freq Modules linked in: kvm iTCO_wdt i8k rfcomm l2cap rtc sdhci mmc_block mmc_core hci_usb bluetooth b44 mii ohci1394 ieee1394 uhci_hcd ehci_hcd usbcore psmouse evdev i915 drm cpuid msr speedstep_centrino video thermal processor fan container button battery ac CPU: 0 EIP: 0060:[<f91f9c3f>] Not tainted VLI EFLAGS: 00010202 (2.6.19-rc6-mm1 #1) EIP is at kvm_vmx_return+0xef/0x4d0 [kvm] eax: e5490068 ebx: 00000000 ecx: 00000000 edx: e5491ca4 esi: 00000000 edi: e5490060 ebp: e5a4fde0 esp: e5a4fd54 ds: 007b es: 007b ss: 0068 Process qemu (pid: 24193, ti=e5a4e000 task=c2286a90 task.ti=e5a4e000) Stack: 00000002 00000001 f7fe1278 00000002 b7f92000 e5490000 00000000 00000000 e5a4fdac 00000000 000000d8 f783a580 e5a4fdac c043b98a bfb93f7c f91fa020 e5a4fde0 bfb93f7c bfb93f7c f91fa0cb 000004f3 c03fb974 e5490000 00000000 Call Trace: [<f91fa020>] kvm_dev_ioctl+0x0/0x1040 [kvm] [<f91fa0cb>] kvm_dev_ioctl+0xab/0x1040 [kvm] [<c03fb974>] error_code+0x7c/0x84 [<c011d469>] kmap_atomic+0xc9/0xe0 [<c018007b>] permission+0x2b/0xd0 [<c01700d8>] sys_swapon+0x978/0xaf0 [<c011d263>] kunmap_atomic+0x63/0x70 [<c011d469>] kmap_atomic+0xc9/0xe0 [<c011d263>] kunmap_atomic+0x63/0x70 [<c015cdbd>] get_page_from_freelist+0x27d/0x340 [<c011d469>] kmap_atomic+0xc9/0xe0 [<c011d263>] kunmap_atomic+0x63/0x70 [<c015cdbd>] get_page_from_freelist+0x27d/0x340 [<c0157af0>] find_get_page+0x20/0x60 [<c015a75c>] filemap_nopage+0x2dc/0x490 [<c0178a47>] do_sync_read+0xc7/0x110 [<c011d469>] kmap_atomic+0xc9/0xe0 [<c011d263>] kunmap_atomic+0x63/0x70 [<c0166386>] __handle_mm_fault+0x246/0x9c0 [<f91fa020>] kvm_dev_ioctl+0x0/0x1040 [kvm] [<c030ae02>] scsi_host_alloc+0x202/0x2a0 [<c018430b>] do_ioctl+0x2b/0x90 [<c01843cc>] vfs_ioctl+0x5c/0x2b0 [<c018465d>] sys_ioctl+0x3d/0x70 [<c0103238>] syscall_call+0x7/0xb [<c030ae02>] scsi_host_alloc+0x202/0x2a0 ======================= Code: 14 0f 87 77 02 00 00 8b 0c b5 00 15 20 f9 85 c9 0f 84 68 02 00 00 89 ea 89 f8 ff d1 85 c0 0f 84 4c 02 00 00 89 f8 e8 31 e9 ff ff <65> a1 08 00 00 00 8b 40 04 8b 40 08 a8 04 0f 85 ae 02 00 00 e8 EIP: [<f91f9c3f>] kvm_vmx_return+0xef/0x4d0 [kvm] SS:ESP 0068:e5a4fd54 msrs: 2 Oh, and I get a ton of these messages with kvm: rtc: lost some interrupts at 1024Hz. 2. I'm not sure if this bug is in the kernel, wireless tools, or the ipw3945 driver, but I haven't changed the version of anything but the kernel. When I do `iwconfig eth1 essid foobar' something drops the last character of the essid, and a subsequent `iwconfig eth1' shows "fooba" as the essid. And it's actually set as "fooba", since I had to do `iwconfig eth1 essid MyUsualEssid_' (note underscore) to get on to my usual network. --Thomas Tuttle
