Yes it occurred in the previous version and yes, I have tried about a
dozen other kernels.
I would rather do some triage to actully identify the issue instead of
getting in an endless loop of trying different kernels in the hope that
some unrelated patch will have an affect.

Title:
Faulty laptop battery or AC throws system cache for a loop
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
After a random period of time after a fresh boot, the system cache
gets corrupted. This is shown by hdparm -T.
Before system cache corruption:
Timing cached reads: 1804 MB in 2.00 seconds = 902.88 MB/sec
After system cache corruption:
Timing cached reads: 258 MB in 2.00 seconds = 129.10 MB/sec
Either the system battery or the AC adaptor is not functioning
correctly, the Dell bios at times indicates that the AC adaptor is not
a valid Dell product, though it is. In any case, the battery does not
charge, but remains at 0%.
