Public bug reported: Binary package hint: linux-image-2.6.20-15-generic
I have Acer Aspire 5101 AWLMi laptop with AMD Turion64 (single core) CPU, and installed amd64 version of Ubuntu 7.04. This bug is perfectly reproducible in Ubumtu 6.10 and 7.04. When I insert PCMCIA compact flash card reader I get the following dmesg output: [ 267.670692] pccard: PCMCIA card inserted into slot 0 [ 267.670698] cs: memory probe 0x0c0000-0x0fffff: excluding 0xc0000-0xcffff 0xe0000-0xfffff [ 267.675119] cs: memory probe 0x30000000-0x33ffffff: excluding 0x30000000-0x33ffffff [ 267.675137] cs: memory probe 0x60000000-0x60ffffff: clean.

I must say that I've not seen this bug in Debian 4.0 and openSUSE 10.2 (both have 2.6.18 kernel) so I think this bug is specific to Ubuntu. ** Affects: linux-source-2.6.20 (Ubuntu) Importance: Undecided Status: Unconfirmed -- Kernel oops when inserting pcmcia CF reader https://bugs.launchpad.net/bugs/111690 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
