Description of problem:
Kernel panic when trying to gzip, scp, unzip, etc. on somewhat large files. 
File size is < 30MB compressed, < 300MB uncompressed.  This started only after
upgrading from the 7.3 stock smp kernel (kernel-smp-2.4.18-3.i686 build) to any
of the recently recommended update kernels (kernel-smp-2.4.18-5.i686 and
kernel-smp-10.i686 builds).  Problem disappears when reverting back to
kernel-smp-2.4.18-3.i686 build.  This occurs on 2 identical (HW and SW) servers.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Tyan 2510 w/ on-board sym53c8xx, dual PIII 1GHz (more below).
2. rpm -Uhv kernel-smp-2.4.18-[5,10].i686.rpm
3. reboot
4. gunzip foo.gz (compressed size ~30MB, uncompressed ~300MB)
	

Actual Results:  kernel panic (see message in "Additional Information").

Expected Results:  uncompress file, return success, and keep running :)

Additional info:

OS: RH 7.3 w/ relevant recommended updates (applied manually).

FS: ext3 on software raid. md0 is RAID 1, md1 and md2 are RAID 0.
