Hi,
every now and then (and more frequently now) I receive the following message on this Atom N270 netbook:
swap_info_get: Bad swap offset entry 0200f8a7
This started to show up a few months ago but appears to happen more frequently now:
4 May < Linux version 4.11.2-1-ARCH 4 Jun < Linux version 4.11.3-1-ARCH 7 Jul < Linux version 4.11.9-1-ARCH 4 Aug < Linux version 4.12.8-2-ARCH 24 Sep < Linux version 4.12.13-1-ARCH 158 Oct < Linux version 4.13.5-1-ARCH
I've only found (very) old reports for this[0][2] with either no solution[1] or some hinting that this may be caused by hardware errors.
In my case howerver no kernel BUG messages or oopses are involved and no PTE errors are logged. The machine appears to be very stable, although memory usage is quite high on that machine (but no OOM situations so far either). As the machine is only equipped with 1GB of RAM, I'm using ZRAM on this system, which usually looks something like this:
$ zramctl NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT /dev/zram0 lz4 248.7M 195.7M 74M 78.7M 2 [SWAP]
I suspect that, when memory pressure is high, zram may not be quick enough to decompress a page leading to these messages, but then I'd have expected a zram error message too.
Can anybody comment on these messages? If they're really indicating a hardware error, shouldn't there be other messages too? So far, rasdaemon has not logged any errors.
Thanks, Christian.
