These from Neil Brown:
patch-A-UmemWarn Fix the compile warning ....
patch-B-0-9-18 Latest Ext3 patches
patch-C-Ext3Fixes Fix some problems with ext3
patch-D-NfsdLookupTidy Tidy up code in nfsd_lookup
patch-E-NfsdInit Tidyup init/exit fof nfsd module
patch-F-NfsdFsid Support fsid= export option to be device
number independent
patch-G-NfsdLocksExplock Change export table lock to (SMP
safe) rwsemaphore
patch-H-NfsdLocksCachelock Lock reply cache with SMP safety.
patch-I-NfsdLocksNfssvc Tidy up locking in nfssvc - preparing for BKL removal
patch-J-NfsdLocksRename protect rename and related operations by kernel_lock
patch-K-NfsdFhLock protect file handle lookup by kernel lock
patch-L-NfsdLocksRacache protect read-ahead cache with SMP safe locking
patch-M-NfsdBKLgone Remove last unneeded bit of BKL from knfsd
patch-N-RpcLists Change sunrpc to use more list.h lists
patch-O-RpcInit Get sunrpc to use module_init properly
patch-P-RpcSvcLocking Tidy up SMP locking for svc_sock
patch-Q-RpcTcpCloseBad Detect and close tcp connections that we

I haven't tried plain 2.4.19 yet. Should I have reason to not trust
these patches?

So could this be taken to mean the issue is most likely software
