CpuTscSync Panic again with TSC_sync_margin=0

[sushilei]

today cputscSync panic again with TSC_sync_margin=0,cputscSync 1.0.6.

panic frequency decreased with TSC_sync_margin=0, but this time pc slept more than 24 hours,then panic.

this is log:

I don't know if something else bring this panic. I met this in Monterey too, and now degrade to Big Sur without any problem. Then, I read the latest issues and found that some issues happened just in Monterey other than Big Sur or older version, for example #1895 . my point is that may be there is another reason for this panic.

[HeartAndSoul001]

And I found that most happened on laptop which has more parts need to be modified, other than desktop.

panic again.And this time pc slept less than 6 hours

[JunqiK]

Yes. Panic again with TSC_sync_margin=0 cputscSync 1.0.6. The args does reduce the frequency and possibility of panic. BUT, it still panic randomly.

[lvs1974]

I have found a better place to sync TSC in the kernel, please try attached version without boot-arg TSC_sync_margin=0. CpuTscSync-1.0.7-DEBUG.zip

[lvs1974]

Must be fixed in version 1.0.7
