Mmmm, you might be right. I'm using a 3com 589, therefore I'm using the ep driver. Unfortunately I don't have a different PCMCIA network card at hand, but I can try to reverse the crash test with my server. Yes, the server is running exactly the same version (4.4-RC) but uses the de driver. So I did and, guess what, the find/cat test on my server over an NFS mounted directory from my Vaio ran without a problem. I've just done a further test. I've mounted a directory tree from Vaio to Vaio using localhost (lo driver) and the test has run smoothly. So chances would be good the bug is in the ep driver. Unfortunately... $ ls -l /sys/dev/ep total 70 -rw-r--r-- 1 root wheel 23554 Jul 17 2000 if_ep.c -rw-r--r-- 1 root wheel 6202 Jan 14 2000 if_ep_eisa.c -rw-r--r-- 1 root wheel 10046 Dec 16 2000 if_ep_isa.c -rw-r--r-- 1 root wheel 4584 Oct 27 1999 if_ep_mca.c -rw-r--r-- 1 root wheel 6950 Aug 9 2000 if_ep_pccard.c -rw-r--r-- 1 root wheel 13935 Jan 12 2000 if_epreg.h -rw-r--r-- 1 root wheel 2667 May 24 2000 if_epvar.h none of the modules belonging to the ep driver has been touched for a long time. Side note. Regarding a different problem I've mentioned in freebsd-hackers I've been told 4.4-RC has got problems with the PCCARD code. Whether that can influence the ep driver is beyond my knowledge. -- walter pelissero http://www.pelissero.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
