Kernel from RH 7.0 destroy ext2fs on Cyrix M II processor
Last modified: 2007-04-18 12:32:37 EDT
I had a machine with RH 6.0+ (this machine works for 2 years on the same
HW without any trouble) and I upgraded it to the 7.0 (kernel-2.2.16-22 and
kernel-2.2.17-14 from updates). The installer decided to use i686 kernel
and Glibc (as uname -m display). The system boot normally but after a
while (say 15-30 minutes) when the system was runnig and there was some
disk operations the partitions with ext2 filesystem (I have only ext2 FS)
went to hell (was almost unusable, e2fsck did not help).
I decided to use i386 libs, kernel (fresh installation). The system run
for 12 or 16 hours and then the same as above - there was a problems with
ext2 filesystem. I decided to use another HW (486 procesor on a different
motherboard) and everything is ok again.
This seems that kgcc produce bad code for Cyrix M II. I did not tested any
of 2.4.x kernels as this HW is in another firm.
Reproducible: Always, update or fresh install doesn't matter
This is high severity bug but 2.2.x is obsolete and there could be some
comment about Cyrix processors when 2.2.19 will go out.
This looks more consistent with hardware than software problems, especially as
its one of the notorious Cyrix heating elements as a processor. Does the machine
pass stress tests like memtest86 ?
It could be possible. I have no longer access to this machine so I can't test
it. The server's HW has been replaced by another.
Just spotted this bug still open. Without reproduceability, there
isn't much can be done, especially since it looks like a hardware
issue likely. Closing bug as NOTABUG for now. If you reproduce
again, and the machine passes a memtest86 test, feel free to
reopen for further investigation.
