 raitobezarius | Given what you are saying, I believe the Lix project already bisected the kernel bug you are looking for, unfortunately, all the commit IDs and answers are trapped behind the kernel lore mailing list browser: https://lore.kernel.org/all/w5ap2zcsatkx4dmakrkjmaexwh3mnmgc5vhavb2miaj6grrzat@7kzr5vlsrmh5/ | 19:51:38 |
 hexa | Christian Theune: ^ | 19:51:57 |
 Theuni | oh? | 19:52:43 |
| * Theuni checks | 19:52:46 |
| Theuni | for me it's behind a guru error 😉 | 19:53:10 |
| raitobezarius | I think you will get a 503 unfortunately | 19:53:10 |
| Theuni | yeah | 19:53:14 |
| Theuni | did this break recently / due to a current event? i've been working with it last week I think ... | 19:53:45 |
| raitobezarius | https://lkml.indiana.edu/hypermail/linux/kernel/2506.1/07850.html | 19:54:24 |
| raitobezarius | thankfully I have found another server | 19:54:31 |
| raitobezarius | To me, this is not a regression, this was always broken, it just takes a lot of I/O in the VM to materialize the regression | 19:54:50 |
| raitobezarius | You can try to revert the "real fix", apply the workaround and verify if this fixes your issues | 19:55:07 |
| raitobezarius | If it does, this is the folio management of 9pfs which is still broken atm | 19:55:15 |
| Theuni | ugh | 19:56:04 |
| Theuni | so yes | 19:56:07 |
| Theuni | in your mail, the last point: "massive io in the guest" is what is triggering in our cases, too | 19:56:22 |
| Theuni | and you mentioning folios makes me weep | 19:56:33 |
| Theuni | i already had a 3 year journey wrapped up of getting an xfs folio issue fixed last year -_- | 19:56:51 |
| raitobezarius | Well, you will be happy to know that the folio code is going to happen even more in more FS subsystems | 19:57:12 |
 Alyssa Ross | Didn't we switch to virtio-fs for VM tests? | 19:57:24 |
| Theuni | linus was not amused when he saw what was going on ... | 19:57:31 |
| Theuni | Alyssa Ross: 24.11 and 25.05 don't seem to be, might it have been more recent? | 19:58:15 |
| Theuni | raitobezarius: do you happen to have a patch set for 6.12.34 around that I can try out? | 19:58:51 |
| Alyssa Ross | Not more recent than 25.05 | 19:59:13 |
| Alyssa Ross | Ah it was buildInLinuxVM, not NixOS tests | 19:59:38 |
| Theuni | hmm. now ... how can i respond to that regression list thread so I get involved there ... o_O | 20:01:56 |
| Alyssa Ross | Download the raw message, open in it your mail client | 20:03:10 |
| Alyssa Ross | Although you might need lore to come back for that | 20:03:32 |
| Theuni | yeah, that's what i was trying to figure out | 20:03:46 |
| Theuni | but the other one at least has message ids | 20:03:56 |
