Tried it on 21-mm2, and it wedged up hard here: [ 66.842587] TCP: Hash tables configured (established 131072 bind 65536) [ 66.842591] TCP reno registered [ 66.845424] initcall 0xffffffff806ff7c6: inet_init+0x0/0x34d() returned 0. [ 66.845437] initcall 0xffffffff806ff7c6 ran for 14 msecs: inet_init+0x0/0x34d() [ 66.845443] Calling initcall 0xffffffff806e28eb: populate_rootfs+0x0/0xea() [ 66.845566] checking if image is initramfs... it is [ 66.978816] Freeing initrd memory: 1824k freed [ 66.979130] initcall 0xffffffff806e28eb: populate_rootfs+0x0/0xea() returned 0.

Had to power cycle. Oddly enough, it boots OK with the same grub line, but minus 'earlyprintk=vga initcall_debug': [ 26.768561] TCP: Hash tables configured (established 131072 bind 65536) [ 26.768566] TCP reno registered [ 26.771502] checking if image is initramfs... it is [ 26.904772] Freeing initrd memory: 1824k freed [ 26.910854] audit: initializing netlink socket (disabled) [ 26.910874] audit(1178725351.514:1): initialized [ 26.911253] VFS: Disk quotas dquot_6.5.1 (My guess is that initcall_debug is trashing some timing constraint that time_init_device is relying on?)
