Update: After playing around with some boxes and a restart later, especially: after installing current ati driver because the one included does not support x1650 card, I noticed things started to behave strangely.
First of all, on this particular board (M2R32-MVP with AMD-crossfire chipset) I can either run one new "sda" type disk (raid not yet invested in :-) or the old IDE UDMA5 disk WinXP is on (natively in MBR). When both drives (IDE and SATA) are physically supplied with power, the windows boot hangs after MUP.SYS (widely discussed in Forums, real reason: the IDE drivers are loaded afterwards and die before they can report it, thus everybody reports harmless MUP.SYS which is only the last driver that is being loaded before UDMA (?) driver(s) crash) Initially, I thought it was the problem having 2 IDE disks on the leftover legacy IDE controller (probably poorly tested...), that is only there to support simple CDR/DVD-Drives I used the opportunity to exchange one IDE for a SATA-drive, calculating that it would be harmless to have only one IDE-Master and one SATA drive. BUT: Grub in MBR on sda fails to chainload the windows MBR on the IDE Master with IDE and SATA drive connected. BUT: With IDE _and_ SATA drives connected, ubuntu boot from sda crashes when trying to initialize IDE with the 0xEC command error, that is specified as "identify drive command", that some people in webspace referred to as "used to query an IDE CD-ROM drive" and thus unsuitable for probing IDE Harddisks. It does not matter whether my ATAPI-CDROM is powered, connected and Master-slave is also irrelevant. So there is a bug in the bios and or kernel (or they just don't harmonize?) which makes the kernel think, any other drive then the boot drive could realistically be only CD-Rom, something like that. Now XFS and broken apt comes into play: exactly the _kernel_ and the two .debs (russian and ukrainian language support) on my XFS root got corrupted when the boot crash occured. However, the _next_ packet I installed (I think it was samba) got _not_ corrupted when I did a clean reboot without the second (now old IDE) harddisk connected to power. The new (UDMA-6) IDE drive now in the other box lives happily with its root still on reiserfs and boots the other box just fine without noticable problems, with or without compiz. But this box is an nvidia system and nForce chipset, now also xfs-ed. I think there is a bios bug and a kernel bug (or no workaround yet, better to say so) wich breaks something for xfs. I do not suspect apt any more (because this works fine on more stable systems. Maybe somebody has a similar hardware and can investigate / confirm. -- Bus error when running Firefox or Epiphany https://bugs.launchpad.net/bugs/133786 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
