Re: [PATCH 1/1] filesystem: Disk Errors at boot-time caused by probe of partitions

I think you may be barking up the wrong tree because IIRC, these requests for data beyond the end of the disk never make it to the drive; the kernel fails them in the block layer. There was a patch a while back to fix the partition detection code to NOT request sectors beyond the end of the disk, but I don't think it was ever merged.

In any case, if you are sure the requests are making it to the drive and causing damage, I hope you give Maxtor and IBM a sound thrashing for using retarded firmware.

Hi Robert,

Yes, I'd have expected that too. I'm particularly surprised the
drive-logic doesn't refuse to move the heads and just report the failure
based on the LBA value.

These are Maxtor drives, but its also happened with IBM drives in
another system with similar configuration, as a test.

During the bug-hunt (which started end of December) I built about 100
kernels trying to track down the root cause, and therefore went through
many reboot cycles.

Several times the drives were 'knocked out' and would refuse to
initialise during POST. The only remedy was to leave the system powered
down for a while - the rest seemed to do them good.

The difficulty I had in debugging was the errors are generated on the
work-queue and interrupt handling side, and it was extremely difficult
to pin-point the root cause because the symptoms (drive seek errors)
occur well after the partition tables have been scanned, and also repeat
themselves several times during system start-up.
