Piergiorgio's note about S5:
> According to the ACPI specifications, chapter 4.7.2.4 "Real Time
> Clock Alarm", the wakeup from RTC, when supported, should work from
> *sleep* state S1-S3 and, optionally, from S4.
>
> Note 3 (same chapter) says that S5 is *not* a sleep state and should
> not be supported. Actually it also says that: "The OS will disable
> the RTC_EN bit prior to entering the G2/S5 or G3 states regardless."
>
> Nevertheless, on all PC supporting the RTC wakeup I tested, all were
> able to wake from S5.

In the check_blocks() loop, current_page is not incremented. Because of this
bug, the loop does not end when the end of the device is reached. Instead it
tries to continue reading, which of course fails, and eventually mkswap aborts
("too many bad pages").
