Yes, on my laptop....(IBM Thinkpad T30) I experience lockups (Kernel -oops once in a while) during bootup. It seems to be the ide-scsi module thats causing the problem. If I ensure that its not loaded during bootup then it seems to be fine. I can load it later manually using 'modprobe -a ide-scsi' If you can figure out whats causing this....it will be much appreciated.
