Yes. I have just tried with 2.6.16-rc1-mm2, and the result is the same.
No root device.
The nosmp-booted kernel looks much much slow than the SMP one, it takes
ages to detect devices like usb ones, and even spent about 20 seconds here:
[ 0.431601] libata version 1.20 loaded.
[ 0.431652] ata_piix 0000:00:1f.2: version 1.05
[ 0.431670] ACPI: PCI Interrupt 0000:00:1f.2[A] -> GSI 18 (level, low) -> IRQ 16
[ 0.431792] PCI: Setting latency timer of device 0000:00:1f.2 to 64
[ 0.431852] ata1: SATA max UDMA/133 cmd 0xC000 ctl 0xC402 bmdma 0xD000 irq 16
[ 0.431950] ata2: SATA max UDMA/133 cmd 0xC800 ctl 0xCC02 bmdma 0xD008 irq 16
>>>>>>>>>>>>> here <<<<<<<<<<<<<<<<<<
[ 0.690451] ata1: dev 0 cfg 49:2f00 82:346b 83:7d01 84:4003 85:3469 86:3c01 87:4003 88:407f
[ 0.690456] ata1: dev 0 ATA-6, max UDMA/133, 390721968 sectors: LBA48
[ 0.696278] ata1: dev 0 configured for UDMA/133
[ 0.701627] scsi0 : ata_piix
[ 1.937443] scsi1 : ata_piix
and it did not detect any drive, so the no-root-device error. This one can be
a detection timeout, but as I say also the USB detection is dog slooow.
Need some info ? .config, or the like ?
