From: Peter Teoh To: LKML Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1224 Lines: 45 Today, both my system (2.6.32.-rc4 from linus git tree and linux-next) bootup blocked indefinitely on: kgdb: Registered I/O driver kgdbts. while booting up. The expected line: kgdb: Unregistered I/O driver kgdbts, debugger disabled. never comes up. My bootup menu.lst: title Fedora (2.6.26-rc4-next-20080530) root (hd1,7) kernel /boot/vmlinuz-2.6.26-rc4-next-20080530 ro root=UUID=d10fe8db-e7d4-4b42-b265-0109a3f3eedf initrd /boot/initrd-2.6.26-rc4-next-20080530.img title Fedora (2.6.32-rc4) root (hd1,7) kernel /boot/vmlinuz-2.6.32-rc4 ro root=UUID=d10fe8db-e7d4-4b42-b265-0109a3f3eedf initrd /boot/initrd-2.6.32-rc4.img and kgdb-related option: CONFIG_HAVE_ARCH_KGDB=y CONFIG_KGDB=y CONFIG_KGDB_SERIAL_CONSOLE=y CONFIG_KGDB_TESTS=y CONFIG_KGDB_TESTS_ON_BOOT=y CONFIG_KGDB_TESTS_BOOT_STRING="y" The same 2.6.32-rc4 image have bootup previously before without any problem. So what could be the potential cause of this permanent wait? -- Regards, Peter Teoh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
