hi, on a friend's laptop, the DVD drive dies after a short while and takes down the main HD's DMA down with it, hda has to be reinstantiated with hdparm -d1 /dev/hda, but hdb (DVD drive) cannot be revived. tried with both kernel 2.6.17 and 2.6.22/23 here is a link to 50kB+ debug info: http://ied.com/linux_dying_dvd_1.txt contents: ( uname -a; lspci; lspci -n; tail -600 /var/log/syslog; cd /proc ; head -100 $( cd /proc ; find ide -type f ) ; hdparm -iI /dev/hda /dev/hdb ) This contents was generated *after* the bug manifested, and manual hdparm -d1 /dev/hda was issued. What else should be in the contents to help you guys pinpoint the problem? Should I include the 50kB+ contents inside this message, or is posting a link better? Can someone please suggest what to try to pass to kernel at boot to work around, so the drive doesn't die? (If I absolutely had to, I would try to recompile the kernel -- I haven't done that in a few years.)
