I have an S3Virage that incurred similar issues. I have backed up all my filesystems, freed up the space, and installed a fresh Lenny with good results so far. Hopefully I will not have time to debug further but if I do, I will follow-up on d-u. 2. I am satisfied the graphics hardware is still functional. I am not sure whether the issue is in the 2.6.32 kernel or Xorg. I do know 2.6.32 breaks my old SCSI support! Sid has finally forced me to return to the good old days. And my Lenny install was not a piece of cake for this experienced sysadmin. "I KNOW engineers--they LOVE to change things!" --Leonard McCoy, M.D. -- May the LORD God bless you exceedingly abundantly!

According to Ron Lee, Debian package maintainer for the svgatextmode package, recent Linux kernels have taken over direct control of the video hardware, and recent releases of X now make system calls to the kernel to change video modes. He refers to it as "Kernel Modesetting Stuff" (KMS). I don't know if that is any kind of official designation or if that's just his pet name for it. With such a massive migration of code from one place to another, we can probably expect some problems in this area. Fortunately, it does not appear to affect my system, which uses an Nvidia TNT2 chipset. This change ultimately let to svgatextmode being dropped from the archive for Squeeze. :-( Perhaps someone else who knows more about it and is listening can elaborate. I'm not saying that this change is the cause of your problem, but it would be the first thing that I would suspect. A similar thing occurred a while back when a lot of mouse code migrated from gpm to the kernel itself. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

I must be missing a crucial list subscription as I haven't heard any of this. I'm not complaining about the instability, merely mentioning my experiences in case they might be helpful to others. I still need to research "sd" driver changes since 2.6.26 to determine if the lifespan of my ancient HW will only be extended by my own driver hacking skills. While that sounds like it would be fun, I would first need to acquire such skills and time to do so is an issue these days. -- May the LORD God bless you exceedingly abundantly!

A Google search of the internet using the keywords linux kernel KMS produced about 136,000 hits; so it's not a secret. But I hadn't heard about it either until I found out from Ron. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
