[1.] One line summary of the problem:
entire 2.4.20 operating system hangs when accessing ide hard drive
[2.] Full description of the problem/report:
my root file system is on /dev/sda3. i have /dev/hda1 & /dev/hdd1
mounted on /u01 & /u02 respectively with ext2 filesystems on everything.
occasionally, i will try to access something on one of these
filesystems and the entire operating system will freeze. this includes
the kde xwindows environment as well as ssh sessions that have no open
file descriptors on /u01 & /u02. when this happens, i notice the
machine's ide hard drive light is stuck on...no flashing...just on
solid. when this typically happens, the machine will have been idle for
a long time but all process not touching /u01 & /u02 are working just
fine. after one of these hangs happens and i reboot the machine, then
accessing the ide hard drives works just fine.
i *do* believe the root problem involves hardware...however, i expect
that the hanging behavior should be limited to only the processes trying
to access the ide hard drives and not the ones that have been running
fine off the root scsi drive. similarly, i've seen this once before on
a completely different machine where there was some problem with the
floppy in the floppy drive. again, the entire machine hung in that
instance.
i built the kernel using the standard tools from a stable debian woody
installation. the full 2.4.20 source was downloaded from kernel.org.

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
[X.] Other notes, patches, fixes, workarounds:
no patches applied.
debian version has been upgraded to sarge and the latest kde. however,
the kernel was built before that upgrade using debian woody.
no workaround.
i boot from floppy using syslinux.
there is a windows 2000 installation on the scsi drive which the machine
will boot into if i do not use the floppy. i haven't used the windows
2000 installation in about 5 months.
i will be upgrading the root filesystem to ext3 (to lessen the chance of
system hangs from corrupting the root filesystem) but leaving the ide
hard drives on ext2 if that helps debug the problem.
it would be my pleasure to help debug this in anyway that i can. i love
linux and look forward to my chance to help out.
