| |
Hi,
symptoms:
I untar'red a kernel source tree under two different directories. After that, a diff -r on the two diretories randomly shows bogus differences although all files are identical. This happens with 2.1.95 and 2.1.96. (the last kernel I used before was 2.1.92 where I was at least not aware of such behavior).
Now, after rebooting 2.0.33, diff reports bogus differences again. Switching computer off and on, then diff: now all files are reported to be identical (as it should be). Seems that 2.1.95 and above has a hardware initialization problem.
First I suspected a bug related to recent scsi/PCI changes. I tried two different scsi drivers (ncr53c8xx and 53c7,8xx) -- with both drivers, the problem is present.
After that, I disabled the L2 cache before booting and the problem disappeared.
Hardware: i486 66MHz, Intel Saturn based motherboard with built in ncr 53c810 scsi controller, kernel compiled without SMP.
Can I do more tests to help tracking down the problem?
