搜索源代码的Uncompressing,在documentation\ia64\Serial.txt里找到以下解决办法
- TROUBLESHOOTING SERIAL CONSOLE PROBLEMS
- No kernel output after elilo prints "Uncompressing Linux... done":
- - You specified "console=ttyS0" but Linux changed the device to which ttyS0 refers. Configure exactly one EFI console
- device[3] and remove the "console=" option.
- - The EFI console path contains both a VGA device and a UART. EFI and elilo use both, but Linux defaults to VGA. Remove
- the VGA device from the EFI console path[3].
- - Multiple UARTs selected as EFI console devices. EFI and elilo use all selected devices, but Linux uses only one.
- Make sure only one UART is selected in the EFI console
- path[3].
- - You're connected to an HP MP port[2] but have a non-MP UART selected as EFI console device. EFI uses the MP as a
- console device even when it isn't explicitly selected.
- Either move the console cable to the non-MP UART, or change
- the EFI console path[3] to the MP UART.
- Long pause (60+ seconds) between "Uncompressing Linux... done" and start of kernel output:
- - No early console because you used "console=ttyS<n>". Remove the "console=" option if your firmware supplies an HCDP.
- - If you don't have an HCDP, the kernel doesn't know where your console lives until the driver discovers serial
- devices. Use "console=uart, io,0x3f8" (or appropriate
