I noticed the same OS behavior on my Release:6.2 box. However it reveals only under certain circumstainces. Description: System will reboot while umount smbfs, but it will happen only if network connection for FreeBSD machine got lost for approximately 12-15 minutes exactly after mounted_smbfs share, and went back just before umount procedure is performed. If to umount just after network unplugged - everything goes fine. If to umount without plugging network cable back everything goes fine. We atach file archive bug.zip that is renamed to bug.txt to send to you (rename it back to bug.zip and unpack to view). The package contains: Kgdb utility information in debug.txt (kernel debug info) Uname -a information in unamea.txt Kernel config in kernel.conf. Dmesg info in dmesg.txt >How-To-Repeat: We managed to repeat a problem under following circumstances: 1. mount_smbfs <smb resource> 2. Unplug network cable 3. Wait for 12-15 min 4. Plug cable back,wait 5 sec 5. umount smb resource 6. System will reboot >Fix: Patch attached with submission follows: PK TseTM)ފqZyћw%yF[L^d-gPC.K)&gW8*灷_<J##oX,2,P&+qY85;`RbRi_x2yxk!Y,S-ɯ^!8fdQ] 6ӻB//NjjtUUe%B T$nWbWJ.e,)QVeY eL۪f%c4]QQQQQQ!ɐdH2$I}D{$((%ZZ7L渗BsugEb=;O{,>]~'EWOPKy.K{Z+KAEV'a'Rƺ&+}-abCc$eZ:~g;NKe[YFh.">]?L}_pr$"Z3钻y]]|r~>&xΝtFYD&諭3WhefwH$6RG77ε:^:*f_˯(Ao^/r·~Mf@2S]8cCݪch~Nb2ԋU 1XOcOrq6wq3;^VF1NAL\]%8jvDzu0++DDc-u,%DxzFn&'Ȱ!qj.h"&&ӗb7fyߞMr*V}%Uj'|,<N3O]4.$!~GG)Һv:L8 xdHi8װϑ:}>OT% E"Ins@><~%LrIXj+iZ$&эfCX2H>,j>3a-|dR*kDTy%ϫv܍>O)Iv8MfqJQU$hòMz*iUq^V}K.w-J<ƻ1*%xx;x.y Ix̏cXolհ3JͩEk_e^wUq:?JG-W! qDso `cQP40̊W=.ᵎ|bT>i|2O>Af>m1rn`#R~T|fC晟BqPGFPKA^n]ː6{mUyl1XE8L6Ge$||4Q"*%RJ3{:,ݪqM[/l!(A&txp+kg2Z,]3&8{K|]lutcLi~jh wX$!x@"I cF'4p9N&C KG)x}/IǶ`H(RTfy4,T$5xwؕo;"8נomXtn-~_Rn{zYh/I2Kh֣0p\|j ,f²$42T`yj@Qؚf@Tx9*sԧ̘Y&۬H7Rx_bC؏d͵McaP3TqˍS_#wH=RB@4]ZCߕ`2-a]@.%2ڙSfJ`|<V<q)ڮZ{bkxQ8ʽt(\Ḛ/áPpr>0- !!0Ca^y+UEB.ei7.f %$7:sn\{n5-<?yl5(#.Q]\]hOƈ)sXsI<(lOɰ\Ǵ(e/^0穆*k_Zf,B<{o7*Jt䜟r+?d+_G<aޟ\>T1, -E1?Rw+2Lgd鄕ٱihZ!t3= ##)jP@hRO]JÑYWuh腫@z.zb;oñ-vBJazM}}Od66vAX:( Ϙz9hVT}QY6<[sg5Nq`={[*j6;m xPdr !Z+*ZttGXU ٧PYW<>@]Y=X1do!Bꫣ&n "y0FM&VNKhfL^t'=^ f8Q=Lyt(y:jHT>B\jQ=Hrjб1$O)TөWyU+D=htMz~a&h_oC@#%$̥.Ո([G0WS7jupTflrz(<Я7{m@ F!_([Mq}{)j7x)Ϧh`{y1KV.*nsڰh4ok_AhqgӀo;@ŖG= quD{M&I)MsIІW?逼g:x`{Xm=H0.%`Dc~c5 [zO9m X: G4ٜ/#?|~CafJHϧ3``=>B!ؓa50i|[p(g}ҖDw??T&F<#T[hY[uk)_Ed-jL1T!CҧVtduQ6hl9z- f+N6!0Ew@m3Y]lE7&G$xs6 ;i<Oj4C *M+h [DTB*K߀|X`Y|E6Ȳ`YsIO >Release-Note: >Audit-Trail: >Unformatted:
