I am working on the -1 timeout patch. It could take another several days for dev and validation in next week.

Please just go ahead to merge this for any urgency. Refer to my inline clarification too.

This line will be whitelisted even when the -1 timeout patch is in because we cannot fix bandwidth issue on AB server and still wanna keep this log visible as heads up.

These errors from callers should not be whitelisted with the -1 timeout patch. Once we have that patch merged, they are still valid errors to indicate a non-timeout root case, or that patch doesn’t do the expected job. The problem of whitelisting  is we could miss other cases in call chains, or cover other root causes of a same error. This is another variant:

[  126.670550] uvesafb: 5000 ms task timeout error
[  126.673310] uvesafb: Getting VBE info block failed (eax=0x4f00, err=1)
[  126.673684] uvesafb: vbe_init() failed with -22

(bz8245 comment #23)

You may want to add “Getting VBE..” lines in this patch too, just don’t be confused when seeing another new uncaught variant.
