2.4.21/2.4.22-rc1: IDE error message on startup

2.4.21/2.4.22-rc1: IDE error message on startup

[Georg Schwarz]

Dear Linux kernel maintainers,

the following problem (aka bug?) appeared in 2.4.21 and still exists in
2.4.22-rc1 (kernels prior to 2.4.21 work fine):

SETUP:
various mostly older PCs (486, Pentium I) and various smaller IDE drives
(can would be happy to more details if needed)

PROBLEM:
With Linux 2.4.21 or 2.4.22-rc1 (not with prior versions using the same
.config however) on startup I get the following error messages for any
connected IDE disk (but not ATAPI CR-ROM):

hda: attached ide-disk driver.
hda: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error }
hda: task_no_data_intr: error=0x04 { DriveStatusError }

Whether I compile with CONFIG_IDEDISK_MULTI_MODE set or not does not
make a difference, by the way.

If there's any more info I can provide (kernel configs maybe?) or things
I could test please do not hesitste to let me know.
I'd appreciate your feedback.

Georg

A change was made to ide-disk.c where it _always_ attempts to do
a READ_NATIVE_MAX call regardless of whether the drive supports
the host protected area feature set in the
init_idedisk_capacity() function.  I submitted a patch to address
this, which is currently being reworked a bit in the 2.6 kernel 
tree and will then be backported again to 2.4.

Given the early nature of the test, its design was to catch devices which
fail to issue an abort for unsupported command sets.  This was to be a
means to flag the device as possible non-compliant.  It is okay to remove
or delete all, as clearly early warnings about standard command sets not
being supported was a silly design on my part.

Making all error messages hide by far is superior than exposing a
potential problem with hardware.  Maybe exposing the facts of media
forensics would clarify the issues; however, it is not that important.
