The alt4_v3 patch from Jeff also still fails here. The screen stays off for 30 seconds, then comes on, but the error-recovery attempts do NOT appear in the syslog as they did with the alt4_v2 patch. The disk LED is still stuck on, and the syslog shows only this, from early on: qc timeout (cmd 0xe1) do_simple_cmd: ata command failed: 4 I've got an errand to run now, but I'll be back again later.
