Still hanging, but more info: Last messages before getting stuck: md autorun DONE kjournald starting Ext3-fs mounted fs w. ordered data mode VFS mounted root (ext3) read-only freeing unused kernel memory 216k freed. warning-unable to open an initial console kernel panic-not syncing:No init found. Try passing init= option to kernel Somewhat silly. There certainly was a console (vgacon) or I wouldn't be able to read the messages. And if it mounted root, then there certainly was an init to run also. SYSRQ P (Omitting lots of time-consuming hex numbers, please tell if those are really needed.) sysrq: show regs cpu 0 Pid:1, comm: swapper not tainted 2.6.14-rc4-mm1 #17 RIP {__delay+4} (Omitted register dump) Call trace: panic+315 vgacon_cursor+0 init+543 child_rip+8 init+0 child_rip+0 SYSRQ T gave me several pages, with no scrollback. Several kernel threads and their stack dumps. Simplified: kedac R running task md2 S md3 S md0 S kjournald S I can provide the full 80x50 page, but I have to write it down by hand so only if someone actually think it will be useful. That EDAC thing was new in rc4-mm1, compared to rc3. I am testing another rc4-mm1 kernel without it. (menuconfig adviced me to say Y to the new EDAC thing, so I did that initially.)
