My NetVista M42 had "weird lockup problems" that were due to timer/interrupt handling issues. I don't have a fix, but I do have a workaround: Boot with the noapic kernel option (no other options necessary).
Try that on your machine and let us know if it changes anything (that is, set the noapic option, but do not set others, don't set nolapic or acpi=off). The following bugs appear to be related: #35274, NetVista 6824 becomes unresponsive after some time, OK after reboot: Exactly the same symptons I had, also same as #71023. #35993, hang on an IBM NetVista PC: Similar symptons. Some have resolved with BIOS update; no such luck for me, I have latest BIOS. Others have use noapic nolapic, but nolapic unnecessary for me. #69526, intel 845G using i810 driver freezes xorg: Similar behavior, esp. comparable to #35993, may be timer/interrupt issue and not related to the 845G at all. #71023, Sparodically slow system clock: I am tempted to mark this one a duplicate of 35274. FWIW, YMMV. -- intel 845G using i810 driver freezes xorg https://launchpad.net/bugs/69526 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
