Subject: Reproducible freeze on 2.4.18

Help! Using 2.4.18 (and verified as far back as .9) - I am getting a process freeze when an application does an fsync. The MagicSysrq sync never completes, so I am unsure as to whether this is a deadlock or not. Dual PIII, I2O RAID controller, 2 GB MEM, ext2 filesystem. The problem is reproducible. I am going to try single CPU with no HIGHMEM.
Any advice would be greatly appreciate. Please CC to [email protected].
Thanks!

Help! Using 2.4.18 (and verified as far back as .9) - I am getting a process freeze when an application does an fsync. Turning off HIGHMEM (the box has 2GB ram) solves the issue. Is there anyone who is interested in learning more about this situation? Please CC to [email protected].
Thanks!

Help! Using 2.4.18 (and verified as far back as .9) - I am getting a process freeze when an application does an fsync. I thought turning off HIGHMEM solved the issue, but I am now getting an identical freeze on an msync. Any advice would be greatly appreciated. Please CC to [email protected].
Thanks!

Please try the -aa kernel patch series.

Also, many people including myself have had better responce from -rmap, but
you should probably give -aa a try first.
