Now I switched my kernel to the one of Apr 12 2003. I rebooted my pc98 box to single user mode, ran "fsck" (I have to do this again and again because of panic) and exitted to multi-user mode. At this time no panic happened. Then, I ran "make update buildworld" in /usr/src (/dev/da2s1g) in kterm on X through the night. No panic. After I wake up, I checked my new arriving emails with Emacs and Gnus. Retrieving emails did not cause panic. But while reading emails, because email backend of Gnus is "nnml" like MH, accessing ~/Mail on /dev/da2s1h occured and got panic. And next "make update" in /usr/src was running in background. I cannot beleive these two are the "heavy disk access" but it may be so. Backtrace from vmcore is almost same as I posted before in this thread. -- NAKAJI Hiroyuki
