FW: Linux 2.6.10 under VMware - NULL pointer.

[Piszcz, Justin Michael]

At first, I thought these problems may have been related to XFS; however, I am now using ext2 and they still persist.

Under the same Virtual Machine, Slackware-9.1, 10 & -current worked OK with kernels 2.6.5-2.6.9.

The current distribution I am running is Debian Sarge 3.1rc2 with 2.6.10.

Any ideas?
