After playing World of Warcraft for a few hours, the display suddenly goes blank and the monitor says that it has lost the (digital) signal. I cannot login again via a serial console from a remote machine because the keyboard has stopped responding, although there is no evidence of any kind of "oops". Alt-Sysrq-S, Alt-Sysrq-U, Alt-Sysrq-B work, so the kernel is obviously still running. This is with Linux 2.6.19.7-SMP, dual P4 Xeon, HT-enabled, 2 GB RAM, Radeon 9200, Xorg 7.1.1 from FC6 (Userspace is otherwise FC5). I first noticed this problem with the March 24 git mesa, shortly before the glsl merge. (NV is still broken, BTW.), and up until last night I thought that I had fixed it by backing out to the March 13 version. However, last night the problem happened again.
Mass version move, cvs -> git
[patch 079/149] drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page and beyond http://lkml.indiana.edu/hypermail/linux/kernel/1007.0/00405.html Hmm, "badness" affecting R200 cards under UMS. I wonder...
WoW no longer runs on R200 hardware.
