Interesting. I installed 2.2.1-RELEASE over 2.2.1-GAMMA (circa Feb.) and had a similar problem. I copied the new GENERIC, reedited and built a new kernel. So far so good. The machine was a Dell box, XPS P133c, IDE, etc. I only installed kernel source over a full source tree from GAMMA. Seemed reasonable at the time, but stupid in hind sight. I deleted the old source. BTW -- this showed how bad IDE really is. Watching iostat with 'rm -r' running showed it blocked most of the time. -- Jay On Mon, 14 Apr 1997, David A.
