Steps:
------
1. Boot in text mode
2. Execute some basic commands like change directory with tabulation

2. Console respond normally

Info
----
We have abnormal numbers of failures in IGT (150 regressions), some basic tests
frequently fails when executed in a loop
Reproduced via ssh (login timeouts or needs also delay)
Not reproduced with kernel boot command line: acpi=off</pre>
