Booting CentOS 7 via iPXE on UEFI (HP G9)
Hi All,
I'm trying to boot CentOS 7 using the images in the images/pxeboot directory. The hardware is HP DL380 G9 in native (UEFI) mode. The kernel boots but always panics as follows: [ 4.138406] List of all partitions: [ 4.155273] No filesystem could mount root, tried: [ 4.178291] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) [ 4.218363] CPU: 6 PID: 1 Comm: swapper/0 Not tainted 3.10.0-229.14.1.el7.x86_64 #1 [ 4.238617] usb 3-1: New USB device found, idVendor=03f0, idProduct=7029 [ 4.238620] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 4.238622] usb 3-1: Product: Virtual Keyboard [ 4.238623] usb 3-1: Manufacturer: BMC [ 4.245099] input: BMC Virtual Keyboard as /devices/pci0000:00/0000:00:1c.2/0000:01:00.4/usb3/3-1/3-1:1.0/input/input1 [ 4.245234] hid-generic 0003:03F0:7029.0001: input,hidraw0: USB HID v1.01 Keyboard [BMC Virtual Keyboard ] on usb-0000:01:00.4-1/input0 [ 4.248961] input: BMC Virtual Keyboard as /devices/pci0000:00/0000:00:1c.2/0000:01:00.4/usb3/3-1/3-1:1.1/input/input2 [ 4.249135] hid-generic 0003:03F0:7029.0002: input,hidraw1: USB HID v1.01 Mouse [BMC Virtual Keyboard ] on usb-0000:01:00.4-1/input1 [ 4.402238] usb 4-3: new high-speed USB device number 2 using xhci_hcd [ 4.566421] usb 4-3: New USB device found, idVendor=0424, idProduct=2660 [ 4.566423] usb 4-3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 4.566691] hub 4-3:1.0: USB hub found [ 4.566715] hub 4-3:1.0: 2 ports detected [ 4.723865] Hardware name: HP ProLiant DL380 Gen9, BIOS P89 05/06/2015 [ 4.755295] ffffffff81813288 0000000087d94de8 ffff881fd320bd60 ffffffff81604516 [ 4.790669] ffff881fd320bde0 ffffffff815fddba ffffffff00000010 ffff881fd320bdf0 [ 4.826215] ffff881fd320bd90 0000000087d94de8 0000000087d94de8 ffff881fd320be00 [ 4.862665] Call Trace: [ 4.874754] [<ffffffff81604516>] dump_stack+0x19/0x1b [ 4.900648] [<ffffffff815fddba>] panic+0xd8/0x1e7 [ 4.923954] [<ffffffff81a455fa>] mount_block_root+0x2a1/0x2b0 [ 4.952414] [<ffffffff81a4565c>] mount_root+0x53/0x56 [ 4.976825] [<ffffffff81a4579b>] prepare_namespace+0x13c/0x174 [ 5.005060] [<ffffffff81a45268>] kernel_init_freeable+0x1f0/0x217 [ 5.036263] [<ffffffff81a449db>] ? initcall_blacklist+0xb0/0xb0 [ 5.064963] [<ffffffff815f2ad0>] ? rest_init+0x80/0x80 [ 5.089948] [<ffffffff815f2ade>] kernel_init+0xe/0xf0 [ 5.114528] [<ffffffff816142d8>] ret_from_fork+0x58/0x90 [ 5.141171] [<ffffffff815f2ad0>] ? rest_init+0x80/0x80 This seems identical to the bug described here https://bugs.centos.org/print_bug_page.php?bug_id=8295 but switching to one of the fixed kernels makes no difference. Has anyone seen this? For reference, here's the relevant bit of my iPXE config: kernel http://blah.blah/allen/vmlinuz ro initrd=initrd.img console=ttyS1,115200n8 initrd http://blah.blah/allen/initrd.img Thanks, Allen |
