Package: grub-pc

Severity: serious
FYI, I can reproduce this bug on my machine under Debian unstable.
To be more precise, aptitude freezes while configuring grub-pc 1.99-9,
because `/var/lib/dpkg/info/grub-pc.postinst` launches
`grub-mkdevicemap -m -` that becomes a zombie (to borrow a term used
in https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/518026).

If so, trying a more recent kernel to compare results would be interesting, too. Unfortunately, not completely. OTOH, I get more reproducible problems when attempting to use the PATA cdrom. Trace left unsnipped for the kernel team's benefit. Well, that kernel does not come from the package, it's a vanilla one with some changes - the VIA VT6415 chipset on my motherboard prevents the system to boot when a HD is connected to it, with the libata driver, so I'm using the old one. Maybe there was a regression in via82cxxx I did not notice before. Will dig.

Can you attach strace to find out what system call it's stuck in, and attach gdb (you may need to build grub2 locally for symbols) to get a backtrace? Unfortunately, neither can complete attaching to the process, and I even have to use kill -9 to get rid of strace and gdb afterwards. Looks like I'd have to reboot and add the strace call to the postinst before retrying ? Bad bad bad :} Maybe we can get some info from the kernel about the syscall details. I have a couple of debugging features activated in this kernel (kgdb notably), I could try to peek via this channel.
