Problem: boot messages fly off the screen before the kernel panic is reached. Possible to write boot messages to a file on a USB stick?
Gentlemen, we all know what a hassle it can be to get all those error messages that fly off your screen upon failed boots. One needs extra equipment etc. Well how about a new parameter that one could add there via typing "e" in grub, linux /boot/vmlinuz... root=... ro single panic=333 save_boot_messages_to_a_file_on=/dev/sdb1 Whereas normally the system would be just attempted to be booted, upon seeing the "save_boot_messages_to_a_file_on=" parameter, the kernel's first job would be to start writing copies of messages that it sends to the screen to some file (default BOOTMES.TXT) on /dev/sdb1 , then proceed to do the booting, making sure after writing its final stack trace to the screen to then close that file and sync it to the disk before giving up and starting the panic wait. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
