Bug#902966: pstore: crypto_comp_decompress failed

[Sedat Dilek <sedat.dilek@gmail.com>]

Hi,

I can confirm to see this on Debian/buster AMD64 with...

     linux-image-4.17.0-1-amd64 (4.17.8-1)

...and removing all dmesg-efi-*.enc.z files in /sys/fs/pstore/...

...and rebooting made the failures in dmesg go away.

Not sure what 'gzip: stdin: unexpected end of file' means exactly in
this context (see below).

I can send all relevant files if needed.

Thanks,
