Description Hans Otten 1999-05-04 08:54:43 UTC

Hi,

In the past I have had two kernel oopses and one file
system inconsistency on a RH Linux 5.2 system, full
install. Kernel package was kernel-2.0.36-0.7.i386.rpm.
Below is the information found in the syslog with respect
to one of the oopses:

I have since killed the Windows partition and reinstalled
Linux in primary partitions. I have also upgraded to kernel
package kernel-2.0.36-3.i386.rpm. As a test I compiled a
kernel as this involves quiet a lot of disk activity, and
all went well.

I see two possibilities:
o running Linux from extended partitions might be a problem
o between kernel packages 2.0.36-0.7 and 2.0.36-3
improvements where made to the filesystem and/or IDE
drivers that fixed my problem.

I still have the original installation that generated the
problems at hand, if anyone is interested.

My main interest is in the interpretation of the kernel
oops.

19990504:
  file system corruption even with kernel-2.0.36-3.i386 and primary
partitions. I am now now suspecting some unfortunate interaction
between cdp (curses based audio CD player) and UDMA. cdp is cdp-0.33-
10.i386

Comment 2 Alan Cox 2000-08-08 13:25:27 UTC

Im assuming this unrelated bug was hardware. If 6.x is doing the same run
memtest86 and if that
says the box is ok file/reopen a bug

And no I have no idea how this bug stayed open so long..
