https://bugs.freedesktop.org/show_bug.cgi?id=106671 --- Comment #16 from Alan W. Irwin --- I was beginning to have some hope that the latest direct access experiment would prove to be stable. However, just now it locked up again after almost 7 days. So the stability is substantially improved compared to before, and my guess is that improvement is due to installation of the amd64-microcode package from Debian Buster for this latest experiment. However, this is still disappointing stability because typically for truly stable systems I achieve up times of 30 days or longer with the only limit on uptime being how often I have to reboot due to kernel upgrades. I have attached a crash report tarball containing dmesg output as well as various log files that captured all log activity before the lockup and the boot afterward. I don't see anything concerning the crash in those log files, but I may be missing something since I am no expert so I would appreciate it if you took a look. I have restarted exactly the same direct graphics access test again (with same versions of graphics stack packages and your recommended idle=nomwait kernel parameter in hopes that the kernel will last longer this time before the lockup and/or I catch more details of the lockup when it occurs. If you would prefer me to try a different variant of this test, please let me know. -- You are receiving this mail because: You are the assignee for the bug.
