I tried to upgrade my laptop to 6.1, and the network boot disk failed. It would throw a kernel oops on starting pcmcia and basically die. Unfortunately, it's kind of hard to get useful information out of the system when the installer's going. (BTW, 6.0 worked fine, AND 6.2beta seems to work with pcmcia) Anyway, I tried upgrading manually, and was able to reproduce it after installing the 6.1 kernel / pcmcia tools. Output is as follows: [root@soro /root]# /etc/rc.d/init.d/pcmcia start Starting PCMCIA services: modules cardmgr. cardmgr[100]: starting, version 3.0.14 [root@soro /root]# cardmgr[100]: watching 2 sockets cardmgr[100]: initializing socket 0 cardmgr[100]: socket 0: SVEC 10/100 Fast Ethernet cardmgr[100]: executing: 'insmod /lib/modules/2.2.12-20/pcmcia/cb_enabler.o' cardmgr[100]: executing: 'insmod /lib/modules/2.2.12-20/pcmcia/tulip_cb.o' Oops: 0000 CPU: 0 EIP: 0010:[<c3040f04>] EFLAGS: 00010246 eax: 00000000 ebx: c27c6ae0 ecx: c1638120 edx: 00000000 esi: 00000000 edi: x2107000 ebp: c216fad8 esp: c216fad0 ds: 0018 es: 0018 ss: 0018 Process cardmgr (pid: 100, process nr: 12, stackpage=c216f000) Stack: c1638120 c2107000 c216faec c30418a7 c1638120 00000000 00000000 c216fb6c c30542e9 0000002d c1638120 00000000 c1638240 00000000 c30546e0 6e000000 c30546e0 c216fb00 00000000 00000032 00000032 00000032 49434d43 74450041 Call Trace: [<c30418a7>] [<c30542e9>] [<c30546e0>] [<c30546e0>] [<c30544ed>] [<c305444c>] [<c30406df>] [<c304a139>] [<c3041aee>] [<c3041827>] [<c3054152>] [<c30546e4>] [<c305444c>] [<c3042ab8>] [<c305405a>] [<c30514f0>] [<c01a47cd>] [<c3051fa9>] [<c01964b7>] [<c0197bd7>] [<c0198f66>] [<c019705f>] [<c019a1db>] [<c019eca9>] [<c019e22b>] [<c019e41b>] [<c011cc3f>] [<c011c58a>] [<c011c8e1>] [<c012e6a1>] [<c0109d08>] Code: 8b 56 04 f6 c2 05 75 0d 66 83 7e 0a 00 74 0d f6 46 0c 05 74 I can't really run a ksymoops on this easily, since the system is kind of munged.
