[18:14] <hggdh> folks, why there is no source xref on kernel modules on a crash's bt -l? Kernel 5.4.0-(1040|1051), at least. I get the source file and line numbers for the kernel itself, but nothing on cifs (our issue)
[18:15] <hggdh> perhaps a different symbols package for kernel modules? But I cannot easily find it
[18:19] <hggdh> for example: https://paste.ubuntu.com/p/YgZWHhFKMH/
[18:20] <hggdh> see frames #11 and 12
[19:34] <thismachine> Does anyone know where I can find an updated list of patches that are applied to Ubuntu's kernels? There used to be one at https://kernel.ubuntu.com/~kernel-ppa/mainline/vXXX/SOURCES where XXX is the kernel version, but that's 404ing now. I had a build script that depended on it.
[19:36] <gpiccoli> hggdh, are you loading the cifs.ko with dbg syms ?
[19:36] <gpiccoli> need to load it on crash tool, with mod -S
[19:36] <hggdh> ah
[19:36] <gpiccoli> hehe
[19:36] <gpiccoli> easy to forget!
[19:37] <hggdh> gpiccoli: dammit! And thank you
[19:37] <gpiccoli> you're welcome =)
[19:40] <hggdh> ah well. I have now hammered it in my failing memory :-)
[19:44] <hggdh> oh, lovely dis -rl now
[19:44] <gpiccoli> heh good!
[19:44] <gpiccoli> are you invatigating some LP ?
[19:44] <gpiccoli> *investigating
[19:47] <hggdh> no, this is for a customer's issue -- the 5.4.0 kernel seems to be missing some patches for CIFS -- on reconnect, if the list of servers is empty, the kernel dies on a unable to handle page fault for address F*8 (all Fs, last digit is 8)
[19:47] <hggdh> you folks should be receiving, shortly, a ping from us
[19:48] <gpiccoli> cool!
[19:48] <gpiccoli> feel free to open a launchpad with the sanitized details, we can start look..
[19:49] <hggdh> ack, will check internally if I can
[19:49] <gpiccoli> ok, nice!
