ALWAYS occurs if I do this:
- Boot with init=/bin/sh
- mount / rw, /usr etc...
- NO modules loaded
- In /usr/src/linux:
make clean
make dep
make dep
... somewhere during the second make dep dies with segfault
(can't umount cleanly, BTW no damage suffered)
also, sometimes, while copying some LARGE tar file (glibc sources :)
some areas are corrupted (all 0xFF)
Hardware:
- Toshiba Satellite 2650XDVD, 64 MB RAM, ~6 GB HDD (EIDE), Celeron 466
RAM should be OK, kernels before approx 2.3.48 work fine.
Using gcc 2.95.2 (a little too aggressive, maybe?... I'll try with 2.7.2)
Same kernel SEEMS to work ok on another machine
(with a lot more of memory =256MB, maybe after a while...)
