I recall seeing similar behavior on a Sun V20z, running 5.x at the time. I have definitely seen a lot of interrupts and CPU usage on the sio interrupt corresponding to serial console. Needless to say there was no activity on the console itself. I think turning off serial console solved that for me. -- Deomid Ryabkov aka Rojer myself@rojer.pp.ru rojer@sysadmins.ru ICQ: 8025844 [-- Attachment #2 --] 0 *H 01 0 + 0 *H =00b;^`@3[m0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 060401182654Z 070401182654Z0_10URyabkov10 U*Deomid10UDeomid Ryabkov1!0 *H myself@rojer.pp.ru0"0 *H 0 sQIk\c!yX6.ܧѧcAƖ THQX>TMrhL2#UK,Uv [CLGsk/=eopy|?aNx*;9;8S06"'+ePzNt; Ȋ.*'Ɔkc$!YuDW27˦UxPT+g|*%qe=T_-%ΈY /0-0 U 0myself@rojer.pp.ru0 U 0 0 *H &7fd·%3WĭcpƐp++N }qfPT0[ 5IXe3A9Gv_*zYvv;bɢ @`E6&2Rߙ00b;^`@3[m0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 060401182654Z 070401182654Z0_10URyabkov10 U*Deomid10UDeomid Ryabkov1!0 *H myself@rojer.pp.ru0"0 *H 0 sQIk\c!yX6.ܧѧcAƖ THQX>TMrhL2#UK,Uv [CLGsk/=eopy|?aNx*;9;8S06"'+ePzNt; Ȋ.*'Ɔkc$!YuDW27˦UxPT+g|*%qe=T_-%ΈY /0-0 U 0myself@rojer.pp.ru0 U 0 0 *H &7fd·%3WĭcpƐp++N }qfPT0[ 5IXe3A9Gv_*zYvv;bɢ @`E6&2Rߙ0?0 0 *H 01 0 UZA10U Western Cape10U Cape Town10U Thawte Consulting1(0&U Certification Services Division1$0"UThawte Personal Freemail CA1+0) *H personal-freemail@thawte.com0 030717000000Z 130716235959Z0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA00 *H 0 Ħ<UsUNʙZ hup [v :aQP 0cZ,p+Z?qV˯< 6$*+w=+>@dקe*TH<a@ dr` 00U 0 0CU <0:08642http://crl.thawte.com/ThawtePersonalFreemailCA.crl0 U 0)U "0 0 10UPrivateLabel2-1380 *H HP . fgCL!6 -6/ P p<ab:~ t%Pb'qW%ݩ9 Oe_N4[5MwV!x!5$ F]_eO1d0`0v0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA;^`@3[m0 + 0 *H 1 *H 0 *H 1 060718155450Z0# *H 1 W2mo5D% a;C`0R *H 1E0C0 *H 0*H 0 *H @0+0 *H (0 +71x0v0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA;^`@3[m0 *H 1xv0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA;^`@3[m0 *H 7W'S1;)* x ~LϬ}Rl&4N{Ԃ aˈCh]gPg|i}.7Ƨcݩs=iC0D N?Y%ooqpuV&Xٝ t (xξD* ~WDFV7e5~ A,ܤƽe$N_Q r`TZJ8Պmc4FqE!d\k% g SD0Cc#B[x^-A D
