For what it's worth there are 3 systems in my home 2 with K6-2/300's and one K6-2/350 and none of them have exhibited any signs of problems at all. I have recompiled the kernel several times and I believe have done 2 make worlds so far. All 3 have the FIC motherboard (VA-503) so that may be related, or maybe you just got a bad chip. > -----Original Message----- > From: Howard Lew [SMTP:digital@www2.shoppersnet.com] > Sent: Thursday, January 21, 1999 1:16 AM > To: Ronald F.
